Every user has a blog. That way, you can find all your posts in one place, as can all the other users.
Blog posts can have multiple images (as mentioned at #9 of this list), can be purred at, and can have comments left on them. Comments can also be purred at.
In addition, you can create a teaser/summary to appear on the main page of the site or your blog, with smaller versions of all your images.
A pane with the author's Name, Picture, and other information (including a link to send a private message) appears in the main post.
