JASC Paint Shop Pro is a simple and easy to use bit-mapped graphics editor. It supports a wide variety of file formats, and photo manipulation functions that were comparable to PhotoShop. It has good support for editing 256 color palletized images that made it ideal for editing web graphics. It was first released in 1990 for Windows 3.0 as just "Paint Shop", and early versions gained popularity through the distribution of shareware releases. It lost popularity in 2003 when 8.0 was introduced with a redesigned UI and in 2004, JASC was acquired by Corel.
