Flickr
Vine Type supports up to 26 different sets of FlickrTM images. This means you can display photos of your vacations in one area of a page and photos of your pets in another area.
Your sets are based on your Flickr tags and Vine Type will return all your photos that share a tag. Is tagging too complicated? Do you just want to show your recent photos? Vine Type does that too.
If you'd like, you can combine Flickr with Vine Type's random feature and display a random sample of a larger collection.
