You've read, perhaps, my commentary on Adobe Photoshop Elements. Well, I was quite frustated when I ran a recent batch process, and not only did my resize/convert job take seemingly forever to complete, it appeared to use nearly 100% of my CPU while it was doing so. This didn't happen last time. I let it run overnight, and much to my surprise, I quickly discovered what the problem was. The 2272x1704 JPEG images I was trying to resize to 1000x750 GIF's were set to inches, not pixels. Ergo, I was creating 300+MB GIF images with a resolution of 30,000 pixels!
This ain't your father's Photoshop.
