Attached Link: Luxology ImageSynth

There's always the ImageSynth plugin from Luxology. It works with programs that can use PhotoShop type plugins. Also, I might mention, it works great, and will do a very nice job automatically, but you do have quite a bit of control over the process if you want it. It's very fast, and was sure worth the money to me.

I have it running in PainterIX, PhotoshopCX, PhotoshopCS, and Photoshop Elements 2.
