I use Realdraw pro - great for graphics, and it can do some stuff in one click that there are 40 step photshop tutorials for doing!
Namo webeditor - got it free on a coverdisk, and find it quite useful for laying out tables and layout out my design
Editplus - Great for tweaking things, fast, easy and I love the way it manages projects and files. Good for php, css, html etc.
Photoshop Elemtnns - pretty good for web graphics, use it with realdraw
Paintshop pro 8 - I have to say I like the speed and simplicity of psp. Sometimes it takes a very long time to do something with photoshop that can be achieved easily with psp. Plus scripting is very useful for creating image sets
Delphi - If I need a program for anything else, IE for making lots of buttons in one go from a templkate, I just code it myself
