Image Resize And Display
Jan 6, 2006
I have to display an image in a fixed spot on my web page. The images are submitted by users, and I have no control over their size (width and height). If the image is wider than 130 pixels, I need to display it with an IMG WIDTH=130 to fit the spot. If the image is less than 130 pixels, I want to display it as is.
Is there a way with Javascript to retrieve the width of the image before the image is displayed by the browser? I know I can preload the image, can I then look at the width before the HTML displays it?

i have 3 text display boxes: (they were originally meant to scroll, but the scroll bars look really ugly with my page)
#scroll {
overflow: auto;
visibility: visible;
left: 350px;
top: 253px;
[Code]...
I'm looking for a solution somewhere along the lines of putting a link in the text box, and when that link is clicked, the text box expands to about double? and then the background image repeats-y (i can manage this part i believe) and then the text is replaced with whatever i want. I havn't worked in javascript (or html) in a long time, so im quite rusty.

I have the following code in a .net page:
<IMG alt="photo" src="Imagesa.gif" height="70" width="70">
When the page opens, the window is not maximized. So when I maximize
the window, the image disappears. If I restore down, the image is
still gone. All the darn coding on this page and I'm getting stuck on
HTML!

I am trying to dynamically resize an image. Here is my code:
<img border="0" src="images/right.gif" width="16" height="100" name="right">
<SCRIPT Language=Javascript>
<!--
function ChangeImgSize(){
[Code]....
The image does not get resized. I've been testing the page on current browsers (IE 8, Firefox, Chrome). I'm certain I'm doing something newbish, I don't really know Javascript all that well.

how to resize a div containing some text by setting a width and height so it would stretch to fill that area like an <img> tag? E.g. when you set the width and height attribute of an image, it resizes the image to fill that area. I do not wish to send a request to a php script to build an image containing the text since it will be slow and affect the scalability of the web app. Oh, and I would preferably not like to use html5 because it is a requisite that I need compatibility with ie7+ (and firefox/chrome).

I have a problem trying to load an image without the image resizing
itself to fit into the window. My simple javascript is as follows:
function viewImage(filename)
{
features = "height=500, width=670, scrollbars=yes, resizable=yes";
photo = window.open(filename, "Preview", features);
}

I need to have an image of a heart on a site that beats, so essentially it expands and contracts. Whats the best animation effect for this? Should I use .animate to resize the image?

I have two images, one on top of another. I would like it so that if you mouse over the image on top (imgB), this image would resize and expand. I have tried playing with jQuery's animate() and height/width properties, but these just crop the image as oppose to resizing them.
<div id="imgA" style="background-image:url(aq.jpg); width:1000px; height:400px;">
<div id="imgB" style="background-image:url(wmc.png); width:200px; height:200px;"></div>
</div>

Basically, i have an image that i want it to be resized when i maximize and change browser size, so it is always centered. I have to use only javascript. I tried many window.resize functions but nothing works. Lets say the image is called 0000.jpg.

I've written some javasript code to resize an image tag. While the page loads the image tag is display: none so a large image wont break the stylesheet before I have a chance to shrink it. onload I call function load1 and you can follow the rest from the code below. This is working in Firefox and Chrome and appears to be doing absolutely nothing in any version of IE.
Javascript after </html> tag:
<script type="text/Javascript">
function load1() {
imageLoaded();
document.getElementById("confImage").style.display = "block";
} function imageLoaded() {
var iW = document.getElementById("confImage").width;
var iH = document.getElementById("confImage").height;
changeImageSize(iW, iH);
} function changeImageSize(iW, iH) {
if (iW > 460 || iH > 460) {
reset dimension of image to fit in div
var multiply = 0;
if (460 / iW < 460 / iH) {
multiply = myFloor(460 / iW, 3);
} else {
multiply = myFloor(460 / iH, 3);
}
document.getElementById("confImage").width = multiply * iW;
document.getElementById("confImage").height = multiply * iH;
}}
function myFloor(n, pos) {
n = "" + n;
if (n.length < n.indexOf('.') + pos + 1) {
return parseInt(n);
} else {
return n.substr(0, n.indexOf('.') + pos);
}}
</script>

I am trying to make a javascript utility where the user can resize and drag an image. A slider contols the size of image from 0% to 200%. And also the image is draggable and the x and y coordinates of the image are immediately reflected on a text box in the page.
I think that this is possible with jquery or other javascript libraries. But was looking for some direction where I can find the best tutorial or examples.

I have a situation where I'm sending full sizes images to new windows from linked thumnails. Using _blank, the window is rendering at a very small size, and the image scales to that size on some browsers.
I want the window to be larger when it comes up, and the image to display maximized (not scaled). I know how to resize the window from javascript in link-side docs, but not in linking-side docs.and no idea how to max the presentation of the image.

I was wondering if there is a way to use Jquery to reduce the amount of images I use on my company website as well as resize them depending on the page they're displayed on. It's just that I feel that's it's very tedious creating 5 or 6 formats for each campaign each with it's own dimensions depending on the page and unfortunately my company doesn't want to implement a Backoffice fed site, which means I have to do it all manually.

I am looking at an easier way to have the background-image for a site be resized so that it looks the same across all screen resolutions (or at least close enough). The way I am doing it now is by using Javascript to get the width of the screen and then loading an appropriate sized image. Looks like this:

I wanted to do an Ajax script to resize and preview and image in an html form. Well, I didn't find how to do with Ajax, so I had to use php.The issue is that JavaScript cannot manage a file field to get the selected file and send it via Ajax. The only way to send a file is submitting a form. To not send all data of the form, the file field must be a separate form from the rest of the data. So it can be automatically sent to a php script, which resizes the image, uploads it and then can display it in a iframe without reloading the page.
Then you have the resized image previewed in the form without submitting all data. And then you can send all data with Ajax, including the path of the previously uploaded image, which is stored as a variable in the iframe.I use one html file and two php scripts, which in total are less than 20 KB.

I'm working with a site which has a centered table which is fixed width at 961px.Now what I need to do is to display one image on the right of this, and one of the left, and make it so that the image trails out to a constant color.
The issue starts when this image (really it was originally one image with white space between the two borders) is displayed in the browser. Depending on browser, resolution, etc, the image became far too wide.
