is there a trick to getting the specifics of threadless file size submission? if it's 640 pixels, then the file size is over 250k. if it is under 250k, then the pixel width isn't perfectly 640. the image is flat, it is in 8 bit, it has been saved as a crappy gif, the worst jpeg, etc... nothing seems to get it to fit. even the template i downloaded is too big! help me!
