Sorry but The Gimp is not as powerfull as Photoshop!
Photoshop features several advantages in color management. It has support for 16-bit, 32-bit, and floating point images, support for the Pantone color matching system, or spot color and support for color models other than RGB(A) and greyscale, such as CIE XYZ. Photoshop features extensive gamma correction support.
In addition, Photoshop contains several productivity features and tools not supported by the GIMP, such as native support for Adjustment layers (layers which act like filters), undo history "snapshots" that persist between sessions, the history brush tool, folders in the layer window, a free transform tool to rotate, scale and move in one tool, and an interpolation code to draw smooth brush strokes using a tablet. The GIMP also requires basic programming knowledge to build an automation upon it, usually Script-Fu (scheme) or Python-Fu, while Photoshop can record your actions and repeat them with a "Play" button.
Photoshop Elements sells for less than 100,-$ and its often included in hardware products like scanners, which means you basicly get it for free.
It does not matter if you use Photoshop, The Gimp or something else as long as the results are good. Most people don't even need 5% of the functions Photoshop or The Gimp includes. Especially if you draw sprites for TTDX. If you just draw sprites for TTDX both programs are way to powerfull!

The Internet Explorer and Outlook Express are free. You can download them any time for free on the Microsoft website. Microsoft even made give away cd-roms.
There are several Extensions for Firefox which are malware and spyware (and widely in use). The guidline to fix security holes in Firefox is very similar to the guildine for the Internet Explorer. The Firefox is not better than the Internet Explorer nor is it more secure to use the Firefox. Its just your personal favour which of them you do actually use.
