BigLouis87 on "search by owner"

I need to write a user page that shows all the images that a user owns, a sort of search by tags (clicking on the word) but by owner. I need it to collect every image a user uploads on my site.
The search form doesn't have a 'owner' option and I can't find a specific function in the documentation.
What function can I use to print them? Any suggestion?
Thanks
