I think that you are responsible for uploading them yourself. I see that someone has set up a QSL collection category on the Wiki, and has populated it with a lot of the QSLs that people, including me, have uploaded. I'd say that's a good place to start. Later you might consider putting links in the articles about particular pirates to the QSL images that you have uploaded. Of course, feel free to drop in #pirateradio to ask for help.
