This is the best good news other than FireFox 3 RC2 for this month so far. Im a loyal fan of gravatar, and I’m indeed happy to tell you all that they do support transparent PNG and GIF gravatars now. A feature which was not available in the past. In the past any transparent area of a gravatar will be displayed as Black which was a major problem for people who wanted transparency.
Now Gravatar.com Supports Teansparency
According to Chris Pirillo from Gravatar Blog He said the following.
After a lot of tinkering, fiddling, poking, and prodding we?ve revamped the image support in gravatar. Now if you upload a GIF or a PNG we will preserve any transparency that might be in the image and serve that image to you as a PNG.
Unfortunately this does not retroactively fix existing images with black instead of transparent backgrounds. You?ll want to re-upload your transparent images, assign the new image to your email addresses. After that, give it about 30 minutes and clear your cache. Everything should work and look just fine.
A note for all you webmasters out there: If you?re worried about what transparent PNG images look like for your IE visitors, I would recommend taking a look at this handy Transparent PNGs in Internet Explorer 6 page which offers an explanation, information on workarounds, and a drop-in javascript which will work for all the images on a page.
