Crop and Resize images using free GIMP program

A common image edit, needed for posting images to Artalyst, is the Crop and Resize of an image to create the 80x80 and 260x170 thumbnails. GIMP can make this extremely easy as you will see below. GIMP stands for GNU Image Manipulation Program. It is generally considered the best free alternative to Adobe Photoshop. The open source program is designed to be as powerful and complete, although arranged differently, as its pricey competitor. GIMP will run on multiple platforms including UNIX, Linux, Mac OS and Windows PC. You can download GIMP for free here: www.gimp.org

Crop and Resize images using free Sumo Paint 2.0

Sumo Paint 2.0 is a great on-the-web image editing program. There are no files to download or install. Anywhere you have internet access you can edit an image. You can edit images from your computer or from a url address. The program is quite extensive for a free, web-based application but it is not as accurate as a quality image editing program that may be installed on your computer like Adobe Photoshop, Paint Shop Pro, or even the open source program named Gimp.
