You can't upload from the internet here. You must download the file to your hard drive then reupload to your gallery. Be sure you have permission to do so, as the rules state.
Yes, it is mine, I drew it all myself. So I uploaded like you both said, but I did it as a .pdf. But then it would only show it in the small size. I changed it to .jpg format and it will show in original. That'll work I guess. Thanks for your help!
