your are lucky if not dealing a lot of images every day
i done the same thing like you do, i use PS for editing & retouching the image and use IrvanView
( imho : freeware and better than powertoy ). You Might Try it bill
But since the last year, i was helping my famaly e-commerce as programmer and web master. Since that, i'm dealing with hundred/ thousand of images every week
so i need tools to help me
After reviewing and testing couple of commercial software, i choose reaconverter.
hope this info could help other who deal with many images in their daily activities like me
