I beg to differ, slightly, with CaptainSpam's writeup. Paint Shop Pro is a paint package very much in the tradition of the DeluxePaint family. It was first released (I think) for Windows 3.1, and each version has added more (largely pointless) functionality. The best version was PSP4. It allows pixel-level work to be done easily, although lacks some of the toys of versions 5 and above. PSP's strengths are that it supports a wide variety of image formats (making it ideal for batch conversion of files), has a thumbnail gallery, and loads extremely quickly (well, version 4 does - its progeny are stupidly bloated). However, as a serious image manipulation program, it is almost wholly inadequate. Photoshop laughs in its face and spills its pint. Forking out more than about £30 for it would be a waste of money, but it's the best no-nonsense paint package for Windows.
