Damn, that's expensive. I tried the demo and was mildly impressed. Its not the kinda of interface that makes you say Wow!. Instead it feels like you've stepped in a way back machine to some Win3.11 world. The usage is painfully slow and honestly its not worth the $1,250 price tag for the light version. That's right, over a grand for the light version. They won't even list the Pro or Enterprise prices.

Better off grabbing a copy of Paint.NET (its free) or Photoshop. And for simple image resizing use the free service over at Quick Thumbnail (new things coming at that site)
