Regarding The Gimp, one of the things that I like about it, that it does a decent job of not only downloading from a digital camera, via gphoto plug-in, also converts the photos into other format. I have used Photoshop, and not too thrilled with the way it works.
I don't think Corel Draw is around anymore, nor the company.

It is scriptable and expandable with different plugins.
I use The GIMP daily for work. I actually am using it for editing short avi files.
