Love the concept, however.......

I very much love this batching app for watermarking my pictures, I also love the fact that I can add my logo, both are great options for my eBay business. What I find that does not work is the processing, it takes forever. I had to delete the app twice because it continued to say it was processing. I do NOT think this app is able to add a watermark & logo on multiple pictures together. I tried it without success. By the way, there is NOTHING WRONG with my iPhone to prevent this app from working properly. I think this is a developer bug.
