Need help with the avatar too. The guidelines mention pixel size, but can you help with what it roughly equates to in kb as a .gif? HAve tried the smallest pic I have on my hard drive (around 5kb) and its still too big. Any pointers?
Following on from what Sunstone said - you can also view the image in Internet Explorer (use file - open, or drag and drop the image) then right mouse click on the image in IE and select "properties" - and it will tell you the dimensions.
