"Well featured portable image editor."
Wide variety of plugins available. Portable version integrates easily with the PortableApps.com control panel.
Very slow to load on a slow machine or one with less than a gigabyte of RAM available. Confusing conglomeration of tool bars for the newcomer.
Since I am not a regular at using any graphics programs I was looking for something portable and easy to use. It is portable enough, but can be a bit confusing to use. Searching through the help files provides some relief, but the help files also mention or show earlier iterations of the GIMP so a user is not confident they are getting the correct answer desired.
