Upload an image for the page. It should be 650x450, in Caliborn's scribble style, and ideally saved as a GIF for size.
Because these are all rough scribbles, the maximum file size is currently 500KB. If you've got a legitimate panel that's bigger, message @porglezomp on twitter and ask them about raising the file size limit.
Your image must be manually approved before it appears on the site, so please be patient. If you include your contact info, I can follow up with you. If you include credit info, it will be displayed on the page if your image is accepted.
Thanks for your contribution! <3
