Just some advice. Gimp is comparable to Photoshop, the two of them each have some features that isn't in the other.

Fireworks is a step backward, whether you're coming from Photoshop or Gimp. A lot of people find this hard to understand, since there's a big price difference.

Fireworks costs: Money
Gimp costs: Nothing

Fireworks does indeed seem 'friendlier' but, if you are currently used to the Gimp, there is no reason to buy Fireworks.

In fact, because you have Gimp, you might as well tell everyone that you have Photoshop, because there is no difference in Graphic Output or Quality.
