Uploading images.

Hi there.I can't seem to upload a screenshot for Spiderman 3 for GBA, the file is 250x160 and is only 10.1kb's.....the file is also a jpg too if that helps, I can't stand it when I follow all the instructions on a website yet still get an error like "0: Image is too large. (width/height)"......it's just stupid really.

Sorry, a GBA screen is 240x160 not 250. I'll go change it now.
