The maximum size of your custom image is 90 by 90 pixels or 19.5 KB
(whichever is smaller).

Although someone else had a similar problem where the file was within the limits, but it still wouldn't upload. Possibly a browser security problem or something. We never did figure it out. But I was able to upload it for him.

If you still have a problem, let me know, and I can do the same again.
