Free! CROPP.ME is a web-based app that simplifies photo-cropping for those hesitant to dabble with Adobe Photoshop or it's open-source brethren GIMP. To start, upload one or more photos (we tried four) and choose up to nine desired crop sizes (i.e. 50x50 for thumbnails but you can also enter custom dimensions). Then go favorite a tweet or two while Cropp.me does it's magic. The intelligent processing technology automatically defines a photo's crop area, but you can review and edit each cropped image before downloading all into a single .zip file.
