I want to export jpgs from the CUSTOM EXPORT dialogue with a watermark. I need these for my web store.

Exporting with PDF OUTPUT does me no good, as the file names aren't saved and it's all in one pdf.

I need individual jpgs, with a watermark. I'm having to buy a completely different program to do this easily, when I know this could happen with Bridge simply. I know I can create actions etc in Photoshop, but the ease of creating and adjusting a template like I can do with the pdf, seeing and grabbing the files I want, and exporting into an adjacent folder with correct file names would be IDEAL through bridge.
