Right clicking on Paul's avatar pic shows that the original image should be 120x120 pixels. For some reason it is stretched to twice it's width. Try using the 250x250 version I posted earlier.
OK, just had a look at the underlying code of the page and the image is dsplaying at 250x141 pixels, that's why it appears stretched. Presumably this is a hang-over from his attempts to upload an avatar pic. I think his profile needs to be set to "no avatar" in order to reset the code, then a new avatar uploaded again.
