Good: It's free, and offers the ability to change the format of the pic. I assume that means resizing and such. Thumbnails look pretty respectable, if it's relatively fast.
Bad: Specifies picture dimentions in pixels rather than megapixels. A lot of wasted screen real estate. I don't like the fact that none of the sliders are labeled. Was any of this designed on paper before programming began? The interface needs lots of work.
