I've noticed several problems with the XHTML image that can be
found at:

(or by validating a valid XHTML page of course)

The first problem is with its file extension. It has none. And when I 
try to save it with MSIE5 under Windows, it tries to save it as
BMP (obviously inappropriate for the web). When I try to save it with
NSN4 under Windows, it tries to save the image as HTML or as a
text file. Neither give GIF as a valid option. I can try it with NSN4
under Linux, but I'd imagine it to have the same problem.

A second problem with the image is that the part where the checkmark
extends off the button isn't transparent. This obviously isn't very desirable.
You can see see that by making your browser's background color be
something other than white and loading the above address for the image.
Setting the white to transparent will also give you some problems because
the checkmark (and button?!? even though it's rectangular?!?) is antialiased
to the white (which isn't necessary either because the checkmark has
45 degree angles).

My personal solution was to use the XHTML icon that I had originally made
before the W3C validator provided one. You can see its transparency working
just fine at the bottom of:

Anyone is welcomed to download the image off my site and use it on theirs.
BTW, if you've use that image before, you might want to download it again too
because I've updated it slightly.
