Random Featured Image from folder plugin?

I’m looking to see if a plugin exists that will allow me to select a folder with images already in it so that it could randomly create a featured image for new posts unless otherwise specified in the post.

For example…Let’s say you have a blog featuring strawberries. And all your posts have to do with strawberries. You have a folder with 150 different strawberry pictures…so this theoretical plugin would randomly pick one of those images unless in the post you specify that you want to manually select or upload a different image…ie, you have a post about blueberries and thus, a strawberry picture wouldn’t be appropriate.

Does such a plugin exist?
