It's been a while since I've done this, but here's what I think you do.
Upload it to Wikimedia Commons.http://commons.wikimedia.org/w/index.ph ... ng=ownwork
Then change the file name on the Weird Al wiki page where it says:
- Code: Select all
|Img = WeirdAlYankovic.jpg
You can also change the caption to add "in concert, 2010" or some such description by changing the Img_capt tag.
Let us know if something goes wrong, hopefully I or someone else can help.
