IE PNG Fix Script simulates a IE5.5+ "behavior" that automatically adds near-native PNG support to MSIE 5.5 and 6.0 without any changes to the HTML document itself.

Main Features Include:

- Automatic activation of transparency for PNGs in the page.
- Support for elements.
- Support for background PNG images (unlike many other scripts!)
- Background images can be defined inline or in external stylesheets.
- Automatically handles changed SRC/background via normal JavaScript (e.g. mouseover rollovers) -- no special coding needed.
- Change support includes CSS 'className' changes on elements.
- Incorporates automatic workaround for elements within PNG-background elements.
- Tiny script (for fast downloads).

Limitations:

- Background repeat and position are largely unsupported, this is due to a limitation in the IE transparency filter. If your background is set to repeat, the PNG will stretch to fill the element, and if it's 'no-repeat', the PNG will display once (untiled) pixel-for-pixel.
- Padding and borders don't indent the PNG image and can sometimes contribute to the distortion problem. An easy fix is to use 'margin' instead.
- A:HOVER transparent images are not supported out of the box. If you want this functionality, I recommend you download the excellent Whatever:hover script. This script will then enable :hover PNG background changes on all page elements when both are applied to the page.
- IE 4.0/5.0 are not supported. MSIE/Mac has native support for IMG SRC but no background PNG support. The scripts does nothing in MSIE7 as it supports PNGs natively.
- Users can't right-click-save processed PNG images, they'll save the blank GIF file if they try that. In some cases this might be a feature, not a bug.
- The script detects the ".png" extension in image URLs. So if you have a CGI script that generates a PNG image, you may have to rewrite parts of the script, or just cache them as PNG files somewhere.
- There may be about a short time as soon as the image loads when images are not transparent, before the IE filter kicks in.

Downloadtube.com Editor Final Note:

IE PNG Fix Script provides PNG rendering support to MSIE 5.5 and 6.0 web browsers.
