JQuery :: Target All Images For A WP Theme?

I need change the following jQuery script to target all images for a WP theme. I found two codes that may do it, but I don't know where to place them.

(sample)

Code JavaScript:
$("img[src='left1.gif']").hide();
or

event.target. As it stands now, the script doesn't load images, the browser takes over and loads the image.

(I've included the original comments in the script for safe keeping)

Code JavaScript:
jQuery(function(){
// Tabs
jQuery("#fbfwTabs").tabs();

[Code].....)
