Mods I did this for you. You can sticky it if you like...it seems this question gets asked every few days anymore...
It may take days, even a week or two, before art you have added appears in the EB database.
Every submission is examined by a volunteer moderator who checks and sometimes verifies the information, examines and possibly adjusts the submitted image, and makes sure the listing conforms to EB standards/practice.
Sometimes hundreds of pieces of art are submitted in one week. Or even one day. Sometimes a few hundred people submit the same new gigposter/art print at the same time as well, and that's not a big help to the queue either.
So, please, if you haven't received confirmation in a few days, just give it a few more before creating a new thread.
Thanks for your patience.
