Sorry I don't have 10 posts yet so you'll have to type in my links.
If you want to go the plugin route, you can do this with 2 WP plugins.
The first one you'll need is NextGEN Gallery, which allows you to bulk upload images and make them into a gallery:
wordpress(dot)org/extend/plugins/nextgen-gallery/
The second one adds a little extra functionality to NextGEN Gallery, and creates posts for each image in a gallery. It also can make dynamic galleries that link to each image post.

Hope that helps.
