I use Ulead PhotoImpact. I think it is fantastic for photo editing from my digital camera, along with a zillion other things that a good image editor should do.
It also has vector drawing, etc.
It is worth looking into when comparing Paint Shop Pro. I prefer the Ulead interface. It is quite the package.
The company also has many other packages for video editing, even quite high end, so when you get in with Ulead, you're not limited.
