Swap Image Has Wrong Aspect Ratio
Jan 29, 2006
I am building a site in Dreamweaver for a client which uses templates
for a photogallery that uses simple Javascript to load images "OnClick"
into a named <img> tag. The <img> tag has no dimensions preset because
the loaded images vary in size and aspect ratio (the images
are all prepared so that they will fit easily within the rest of the page
layout, using their actual dimensions).
This all works just fine on Firefox (Apple), but on Safari and Mac IE
there is a problem. When image-2 replaces image-1 (using MM_swapimage),
if image-2 has the same height but a narrower width than image-1, then
image-2 appears with image-1's width. Both image-2 and image-1 have
the same height, so the display of image-2 now has the wrong aspect
ratio (everthing looks "fatter").
I haven't checked Windows browsers yet. I searched around and
haven't seen a similar issue. Anyone know about this, and a good workaround?

This slideshow works fine except that it keeps the aspect ratio of the original pic image. If original image is a portrate all photos are portrate size, even landscapes. If original is landscape, the same is true. The script works correctly when viewing in MS FrontPage. After FTP uploading problem appears. Code:

I've been working at this one for a few days now, and I keep getting the same puzzling results on what should probably have been a simple issue.
My page has images I've loaded at the top and set to {display: none}. The eventual goal is to create thumbnails that will maintain the original images' proportions, but fit within 150x150 px (this is for an artist's gallery page, so it's pretty important to keep the thumbnails looking like the originals). Obviously, the first thing I need to do is get the images' heights and widths. I've tried to do this by iterating through the document.images array and just getting the widths and heights, but for some reason I always get 0 x 0 for the first image. I've tried fixing this by inserting another image before it and then starting the loop at 1 instead of 0 (so it excludes that first image), but I still get the same value. I even tried setting the script to "defer" so it wouldn't run until the page had loaded. Same results. It also doesn't seem to matter whether I ask for document.images[x].width or document.images[x].naturalWidth. The same thing happens either way. Does anyone know what's going on? There's got to be something I'm missing.

so im almost finished my first site! very excited. its for my dads business, hes a screening contractor.actually i doubt he will get any business out of it, even once we get our real domain name and everything because i don't even know how to get Google to like it. its OK though, its mainly just a practice site for me anyways before i make a resume site for myself. anyways, this mayt sound like a flash question but i asked on flash sites and they have no idea, and i think it has more to do with how i embedded the flash. yoy see, it consists of 3 divs, an html content area, and a flash banner and a flash menu, which stretch depending on the window size to keep their aspect ratio. its that streachyness that i believe is causing the problem. everything works exactly as planned in Firefox, chrome, and pure flash player. but in IE, safari and opera, the size and position of things are way messed up! (only really care about IE). the edges of dynamic text are slightly to the left or right and hanging behind things because of it, same with some movie clips and when i didn't want things to appear on the stage i set their x position to be the length of the stage,
i think that ie is calculating the size onresize incorrectly. heres the site, take a look at the the script file:[URL]..

Has anyone got any suggestions for keeping aspect ratio when scaling an image. I want to use it on my 'advert full details' on my website. This page displays an image the user has uploaded to my database, but sometimes I get really hugh images uploaded! When I scale them using % in Dreamweaver I lose the aspect ratio!

displaying images properly maintaining its aspect ratio?
My requirement:
===========
I have a table with single cell (means single row and column). I have to display image inside this cell. But when I do so using the below mentioned statement, the image expands and cover the entire cell area.
<table border=2 width= �600� height= �400�>
<tr>
<td> <img src= �MyPic.jpg�> </td>
</tr>
</table>
I will be loading different images inside the same cell, all having different height and width.
if you know how I can do it. I will be happier if you can paste the code here

Is there a way to create a div or some container in which there will be an image such that the image fills the container but retains its aspect ratio? So if the container is 100px x 100px and an image is 200px x 100px it will be resized to 100px x 50px. Conversely, if the image is 100px x 200px then it resizes to 50px x 100px. An image of 400px x 50px becomes 100px x 12.5px and so forth.
The issue is I have to dynamically build the container pulling images from an image folder. The images can come in all sizes. But I want to make sure they all fit in the same square 'box' without distorting the image.
There is text and a button below the image and I want them to stay in the same 'spot' on the screen without being moved around because the height or width of the image above it grows/shrinks to accommodate a change in either the height or width. These can change but not outside a controlled 'box'.
Maybe there's a way to get the actual size (through Javascript or something) then calculate a percentage to resize the image to?

I'm trying to size an image to fit the browser window. It will be the only thing in the frame, so it doesn't matter if it's the background or not. I've found quite a few ways to have the image automatically resize itself where it either gets cropped off or changes ratio to stretch, but I've not found anything where it'll keep the full image and ratio and just have bars top and bottom or sides.

I've set up jcarousel and configured it to work how I need it to, apart from one thing; I need the images to keep their width - height ratio when the browser is resized.
I'm using the Flexible carousel configuration and the width of the images changes appropriately when the window is resized, but the height stays the same, I need it to change.

I am a complete novice with Javascript, but am trying to work out how I can get a button to swap to another image when clicked, and each image have a different URL attached. I want to use this to toggle the bgcolor of my page using this script:
Code:
<script type="text/javascript">
<!--
function createCookie(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();

I am trying to make a point and click javascript game. Basically what I want is to have one image displayed on screen at the start (room1.jpg). When you click on a door on that image, I have an onclick event to change the image to a new one that shows the door open (room1_a.jpg). What I want is that when you click the now open door, to display the next room in the game. The only solution I can think of is some sort of nested onclick event using several image maps, but I am fairly new to Javascript and I am not sure if that is possible. What it all comes down to is I want to display each incarnation of each room in the game in the same window without having to reload a new window for each room. I hope that makes sense, if not I can try and clarify. Below is the code I have so far. And as you can see all that does is display the open door when you click on the image. I have not done any of the image mapping yet.

I am trying to put together a purse shopping site - I would like to have the various views of the same purse in thumbnails under one image then when the customer clicks on the thumbnail the larger image will go into the viewing area. The general layout is like this page - [URL] So when someone clicks on the smallest image I would like it to replace the other image on the page and the larger image becomes the thumbnail. How is this accomplished?

I'm trying to use javascript to load an image on a webpage when another image is clicked on, just like an image gallery and just like this except I don't need any text: [URL] I copied the example above but when I click on the smaller image to load the larger one it works for a fraction of a second (I can see the image load in the right spot), but then the browser goes to the URL of the image instead (showing it on a blank page).

I'm failing to get a pure CSS way to achieve this, so trying JS. Several small images in a row, each different. Want mouseover to:
1. change each image to different image on mouseover (each image has its own mouseover image version).
2. produce different paragraph of text below row of images on each mouseover.
I can achieve it with mouseover on text links or on an image, but not with the two events, viz mouseover image swap + mouseover text swap. Would also want to be able to style the text.

I have four links that use graphics to create an unvisited and visited state (using CSS). The link actually changes a section of text elsewhere on that page, so the user doesn't leave the page. The clicked, visited graphic reflects what text you are reading. You can then select a different link, and new text reflects the link you clicked on. What goes wrong is that if you click all four links, you eventually get all four visited graphics showing.
What I want is this. You click on the graphic and the graphic changes to visited. You then select a different link and that state goes to visited but the previous link that is visited too, changes back to unvisited. Therefore when you click on any link, that visited state is shown, and all others always reset to unvisited. The results is that the visited graphic reflects the current text on that page.

I am looking to find a javascript that image swaps 4 button images that are to be used as links.
There will be an unvisited button (color of my choice)
There will be a hover state which Is green.
There will be a visited link button that is purple.
There will be a currently active page button that will be red.
I have a script that works for 3 of the for states.
The script that I have also will not keep the purple, visited state, as standard text based links will when a page has allready been visited.
Does anyone have a script that will work for what I want to do for all states.
I don't know how to build a script of my own, but plan on learning.
Does anyone have a script that will work for what I want to do for all 4 link/swap states that I want incorporated?

capturing just the file name rather than the entire path of the SRC on my input type="image". Basically when I hover over an image, the Default Image should change to the image being hovered on. Here is my code, can't quite get it to work. Sorry I'm very new to JavaScript

Lets say I have two images in a box
<body>
<div id="box">
<img src="image1.jpg" id="image1" width="100" height="100" />
<img src="image2.jpg" id="image2" width="100" height="100" />
</div>
</body>
When I click on Image1 I want Image2 to get replaced with a new image, called Image3. So I tried this code:
[Code]...
But instead of replacing the image on click, from some reason it replaces image2 with image3 from start/load.

I'm looking for a solution that can be used in a calendar/gig guide
scenario where each day is represented by a dot image. Now this dot must
do the following
1. When the mouse goes over the dot image it swaps to the mouseover dot
2. When the mouse goes out of the dot image it restores back to the
original img
3. When the img is clicked the dot image is swapped with another image
(different to the other 2) that will remain there even when the mouse
goes out of the image

I have a portfolio page which loads a dozen thumbnails and one large image.
A friend helped me code a script (below) which will swap out the large image
(named "imgLarg") when a different thumbnail is clicked. Both the thumbnail
and the enlargement are identically named, one is in /thumbs/ and one is in
/enlargements/ - tricky, huh? ;-) What's the easiest way to make this work
in other browsers as well?
<script language="JavaScript">
function enlarge() {
oSrcElem = event.srcElement;
imgLarge.src = oSrcElem.src.replace(/thumbs/,'images');
}
</script>

Below is the routine I am using that when invoked swaps images for other images:
<script>
function swapImage(swapContName) {
if (swapContName == 'mainImage1') {
[code]....
But one of the images I would like to vanish (using the empty spacer.gif) has a border:
<img id="instructflag" border="1" src="FLAG.gif" width="23" height="15" align="left">
It must have this black border, but when it gets swapped for a blank, I am left with the black square. how to vanish the border along with the graphic?(I have some vague idea that "border" is not used any more, but anyway...).

Just want to swap an image (thumb) for a larger one - in the same spot - then click on the large image and go back to the small one.
Nothing I have tried works but I KNOW it can be done - can't it?
