Bleh... JPEG images = No love from deviantART

I got finished with my little pixel self-portrait yesterday, but I can't submit it to my account.  Why?  'Cause it's a JPEG image.  Now, I don't really know what JPEG means, but I've been stumped trying to have it as part of my little collection of deviations.  Help, please?


Oh, and this is my last weekend of my summer vacation before going back to school.  Keep your fingers crossed for me!
