Better Image Detection

Just a quick note on a subtle improvement…

In the past when you have uploaded an image to gravatar.com that was not a png, jpeg, or gif, we presented you with a big fat error page (which nobody, ourselves included, likes to see.)  So as of now we do some back end trickery to attempt to get any image you try to use into a format that we can handle.  It wont work with every possible image type, but most of the really commonly attempted ones should be handled (such as svg, bmp, and tif!)

Happy uploading!
