I have been coming across these galleries too, seem pointless to me.Edit:
Oh I see the problem now, so it doesn't go to all images but to galleries instead... I see.
Nope, still think it should be deleted. I think everything can be sorted into galleries anyway, I don't see what images you would have that wouldn't fit in a gallery.
For Dragon Ball Z characters I'm using these galleries:
- Dragon Ball Anime
- Dragon Ball Z Anime
- Dragon Ball GT Anime
- Concept Art
- Official Art Work
- Fan Art
I don't think anything else is needed. What other types of images are there? Just use galleries like those and we should be fine I think.
