Correcting/Editing Photos Categories?

[Magaman]

So overall really great beta, not many horrible issues or bugs. One thing I'm noticing in photos in the categories could be improved with some manual intervention. For instance a Motorsports and NASCAR category was created, all with the same photos, I'd rather they be combined, but can't seem to find a way to do so. Also search isn't always dead on, searched for " Dogs" it came back with some pictures of my cat and lions at the zoo, close, but not perfect, again though no way to tell it no, those aren't dogs.
