Best image gallery plugin for me.

Hi there
I run a satire/gossip blog and I need to be able to quickly and easily upload pictures, tag them, and add them to a gallery.
Idea is, Say i have 10 Britney Spears Pictures, I want to upload them all into a gallery tagged britney, then i want to insert some of them as thumbs into a post.
How would i be able to do all of this from the WYSIWYG editor?

Thanks so much in advance.
