IE7.js is a JavaScript library to make Microsoft Internet Explorer behave like a standards-compliant browser. It fixes many HTML and CSS issues and makes transparent PNG work correctly under IE5 and IE6.
Current version: 2.1 beta4.
Upgrade MSIE5.5-6 to be compatible with MSIE7.

The script only fixes images named: *-trans.png
If you want the fix to apply to all PNG images then set a global variable as follows:
var IE7_PNG_SUFFIX = ".png";You must set this variable before including the IE7.js script. Alternatively, you can set the variable inside the IE7.js script element:
<script src="IE8.js">IE7_PNG_SUFFIX=".png";</script>The suffix will ignore query string parameters. For more fine-grained control you can also set IE7_PNG_SUFFIX to a RegExp object. If you want to use an alternative PNG solution then set the suffix to something that cannot possibly match:
var IE7_PNG_SUFFIX = ":";By default, the PNG will be stretched (this simulates tiling). If you want to turn this off then set the no-repeat property as follows:
div.example {
background: url(my-trans.png) no-repeat;
}Unfortunately, the transparent background image cannot be tiled (repeated) using background-repeat. Nor can it be positioned using background-position.
