It is a program I also use and it is perfectly reliable. Yes, Photoshop is good, but people with fashion and similar sites get very tired working on images. I edit 50 images at once with this. http://www.fotosizer.com/
- Rotating images
- Adding bulk watermarks either as text or logo
- Cropping image edges, making them oval, etc.
- Many operations like automatic resizing can be done.
There are warez versions on the market too; for this, you can search for bulk watermark and check the site called abdullahcali, but I think you should buy it; it is a program that deserves the money.
