categorization?

Can we separately categorize the galleries by animal?

For e.g., separating galleries by Dog and Horse contents.

If someone knows how to code it, a booru style gallery would be nice. This would allow visitors to filter out what they don't want to see/ filter in what they're interested in. Of course this should function as a separate page on the website but still a part of the website altogether.
