A post represents a single file that's been uploaded. Each post can have several tags and comments. If you have an account, you can also add a post to your favorites.

When you're not searching for a tag, by default the tag list will show the last few images added to the database. When you are searching for tags, the tag list will show related tags, alphabetically.
