I'm looking for a desktop program that will let me tag and search images on my computer the same way that's used by this site.

It would be really useful for things like harddrive image browsing, everyday photos, reference images for art, and sketches. I've tried using just folders, but the downfall there is when things fit into multiple categories.

So far the best I could find was picasa 3, which is no longer supported, not that great of an image viewer, and can't play gifs. And downloading it was a hassle because you have to find a download from a third party.

I'm just looking for something that has a simple image tagging system,is light weight, runs on win 10, can support animated gif, jpeg, and png, and preferably doesn't look like hot garbage.
