I regularly scan the covers of my doujinshi so that I can attempt to avoid purchasing duplicates (although you might be surprised at how often I still fail at that).  I migrated it from my previous private location, and you can access the gallery here.

Feel free to request scans; however, please remember that I scan when I can and what I want, so there is no guarantee I’ll get to it anytime soon.  On the other hand, the more people who request something, the more likely I am to move it up in my queue.  Just remember, be polite.  :)
