PNG
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";
<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) usingbackground-repeat. Nor can it be positioned using background-position.
