The thing that I've been fearing to happen...
So, I see that my warning to credit sites in the Image Submission page still was not enough.
Kurorin, if you can PM to me the links to the images in the gallery which need to be credited to your site, then I'll remove each of them in the gallery. There are still a bunch of unvalidated images in the gallery and I'm not sure if they're also from your site. I'll just assume that it's from yours too if the one who submitted them is the same one who submitted your images uncredited.
Sorry for the troubles this had caused. I'll take more extreme measures in the gallery's image submission rules now. Also, I think it really is a good idea to watermark your images especially if you don't want them redistributed on other sites. I do that on my episode screenshots so I understand how it would feel to have your images stolen from your site.
To all other gallery members: No more submissions will be approved unless you mention credits in the description. If you just scanned it by yourself, then tell it on the description. If I hear reports that you're stealing images or not crediting correctly your submissions then I'm afraid I would have to delete your account in the gallery. And I really hope I would never have to do that, so please just do the right thing which is -
give credit.
