Paint Shop Pro is a low-end Photoshop-style package, and it is the most popular image editor available for Windows. It's a shareware product, so it is very inexpensive for the majority of its users. Although it is distributed as shareware, it is also sold widely through desktop publishing and major software catalogs. While in many respects it competes with Photoshop, it can also work as a good complement product for those who also use Photoshop. It's a much smaller program (memory-wise), so its quick load and easier-to-use interface make it great for doing simple jobs where you just don't need all the features of Photoshop.
Paint Shop Pro is used to create graphics, process screenshots, create and touch up Web images and logos, and much more. Paint Shop Pro 5.0 with Animation Shop is the latest version of the software and is currently available in public beta.
