This is not exactly MediaWiki-l related per se, so please ignore the reply-to and answer me off-list if you can.
The PNG logo on my Monobook installation as well as the one on the wikipedia sites (jigsaw globe) has an alpha channel and works equally nice in both Gecho-based browsers as well as M$ Internet Exploder. I can't seem to create one for my site. the best I get is a PNG that is transparent on mozilla but has a weird grey back on MSIE. can anyone clue me in on where I went wrong and what is the correct procedure to get a cross-browser compatible transparent PNG? I have both Gimp and Adobe tools available.
Thanks, Ira.

I wasn't sure of how much of your address was antispam fake material... :)

MSIE on Windows accepts 8-bit palettized transparent PNGs only. I wrote up a quick howto for creating these in GIMP: http://meta.wikipedia.org/wiki/Fixing_transparent_PNGs
Or you can just use a GIF. ;)

none of it, I get everything in this domain. for years it was a wonderful way to sort mail and block spam but now it's a victim to spammers who guess random addresses. I need to switch from inculsive to exclusive filtering :-(

i.e. PNG should disguise itself as a GIF and I lose the alpha channel for 1/0 transparency? oh well...
tested, works, thanks :)

Heaven forbid!!! (and RMS too)
There are IE hacks, using javascript/css, allowing IE to correctly display alpha channel in pngs. See for example: http://homepage.ntlworld.com/bobosola/ or: http://www.mongus.net/pngInfo/

Yes, we've even tried these. Unfortunately they seem to be unreliable; doesn't work at all on some IE versions; throws up security warnings sometimes; may even crash.
I think it's disabled currently.
