It'd be great to have it in the same database as danbooru since sometimes we have trouble IDing artists or where the image comes from.
I made a separate database now for konachan. It'd actually be a little easier to make one for moe.imouto too now instead of combining it. And anyway I plan to add a multi-search feature that combines search results from all databases in my system.
If you want it combined just to find your images on Danbooru, you could instead add a "Find on Danbooru" link that goes to db-search.php with your thumb (like the hidden "Similar images" link does now). When I have the moe.imouto thumbs it doesn't even need to get it from your site to do that. Though if you'd still like it combined anyway, I can do that, no problem. Though then you couldn't search just for images on moe.imouto, you'd also get Danbooru results. Anyway, let me know how you'd like it done.
You'll probably need to register since I hid loli images from unregistered users.
I already seem to have a privileged account there. Not sure how that happened... apparently I signed up in December but I don't know how it got privileged access. Oh well, it accepted my username and password so I guess it's my account anyway.
