As you may know FUDforum so far as used gif images for it's buttons. I am considering switching to PNG and was wondering if any of you had any thoughts/suggestions/etc... on the matter. Basically anything to help me make up my mind.

It is said that IE doesn't support transparency of PNGs...
|
Actually it does support normal transparency, what it does not support is alpa transparency.

Animated PNGs are called MNG (iirc), however FUDforum does not use any animated graphics, so this should not be a problem.

gif is still under patent in several countries, most of them are expiring, but there are still restriction.
but beside of that we can do this compare:
Gif
+ old known format
+ Most UA can render it
- Only 256 colors
- Only one bit alpha channel
- Un-free compression (LZH)
Png
+ True color
+ 1 byte alpha channel
+ w3c recommendation
+ a open format
- IE can not render it correctly
Ok, I haven't consider everything, but this is my point of view, I recommend png rather than gif.

GIF patent only affects applications generating the file, not the usage of the gif files.
My primary reason for considering the png format is that icons used by FUD come originally from KDE. Normally they come as alpha-transparent PNG images and they loose some of their 'shine' when converted to GIF.

I got a JavaScript hack that makes alpha transparency work in IE 5.0+ on MacOS and IE 5.5+ on Win32. Based on analyzing logs of few sites I got access to 5.0/5.1 IE is pretty rare now a days, only about 5-10%.

Users using IE who have javascript disabled will still see the pngs, they just won't look as pretty as they do with JavaScript. I should also mention that far more important things such as FUDcode formatting tools absolutely couldn't work without JavaScript.
