How should PNG images with an alpha channel be handled? I've created some nice images, but now IE6 users are complaining that they have a black background. If I convert them to GIF/PNG-8 images they have an ugly edge, which doesn't seem fair to Firefox/Opera/IE7 users. Is there a better solution, such as MediaWiki automatically converting images for IE6 users?
The best compromise is to create a proper alpha PNG but use a set background color more appropriate than black (i.e. on Wikipedia, probably white). IE6 users will still see a jagged transition, but it won't stand out enough for them to complain.
Also, links to Firefox, Opera, etc cost you nothing to distribute. :)
