>I know. It's the picture I am trying to replace it with that I am having trouble uploading. Do you happen to know what the UT requirements are? I have tried to upload a picture resized down to 44 x 53 pixels, as specified on the picture upload page, and it is still rejected as being too big. What I am trying to find out now is whether there is a file size limit and what it is.

Now it looks like you have succeed. This is much better resolution. BTW, you can also supply bigger picture (I don't recall requirements).
