Publisher review:png.js attempts to replace GIF images that have a class name of png. png.js attempts to replace GIF images that have a class name of png (ie. img src="image.gif" alt="" class="png" /) with PNG images where supported.
In the case of IE:win32, the necessary filters are applied which enable alpha transparency (a big PNG feature) to work. Disappointing on MS' part that it isn't supported natively, but oh well.
Restrictions
- PNG alpha transparency only supported under IE 5.5:win32 and up.
- Image width and height must be specified under IE for PNG to work.
- PNGs as background images may break under Netscape 6.x.
- PNG backgrounds will break under IE:mac. (eg. on a DIV element - known browser bug.)
- PNG backgrounds do not tile under IE:win32.
- "none.gif" placeholder image required for IE:win32 (due to proprietary filter crap.)
