Viral image sharing site Imgur today rolled out new user-driven tagging functionality that will let you create custom galleries and searches based on your favorite tags.

Uploaders can add tags to their own images, and users can vote on or suggest new tags. The tags will also double as filters, so that you can exclude certain types of images from a gallery.

Meanwhile, Imgur has also updated its search function with new features. Now you can sort searches by title, tag, image size and image type. You can also search for the text in some images, such as memes.

The addition of tagging should help Imgur monetize its site, as provide extra data for advertisers. For instance, marketers could use the tags to piggyback on the latest viral trends or micro-target certain categories.
