I switched from PC to Mac around 8 months ago. I do a lot of digital photography and often take these pictures in 5mp size. Sometimes I end up wanting them at that size if I do a special project but frequently I end up making them smaller. On Windows there was a Windows XP powertoy called Image Resizer. It added a option that if you right clicked on a picture you could change it to 1024*768, 800*600, or 640*400 and I often chose the smallest option. How can I go about doing this on the Mac? I sometimes do a batch resizing of 100 pictures at once so I want something easy. I thought it would be built into iphoto but I can't find it.
