Can a featured image be set based on an image URL? I've imported my old blogspot blog with hundreds of posts (only 22 published right now) and many more images, but because none of them are in my media library, they do not show in my slider.
Is my only solution to add the images to my media library, and then set a featured image (which sounds like it could be a lot of work!)

I don't think this is specific theme support, but feel free to move...
