Well, ultimately I think there will be some manual editing involved. But I think you can cut your manual editing a bit by trying to pick up on some clues. A lot of time, pics can be assumed to have some relevance to the page they're on. So, at w:c:tardis, it's virtually a dead cert that the pics at Martha Jones will probably go into category:Martha Jones images. So you can use a bot to put every file on that page into that category. You can also save yourself some time by going to pages where it's likely images of Martha might appear, and using the bot "semi-automatically" to approve each pic.

I don't know what your wiki is, so I don't have any more specific advice to give you. But you can use a bot to logically categorise files by page and then check to see the progress you're making on whittling down Special:UncategorizedFiles. After not so long, you should find that the list isn't so long that you're afraid of tackling it manually.
