Mark,

I had the same problem in the begining, but I now try and use my own photo's or other photo's where possible for things like the trolley, stairs, missiles etc. and then extend them as necessary. I use them for colour match to get the right colour when I need to make a custom image as well.

Other than that I just use PSP and DXTBMP. One thing I have learnt is that I start with a black background and use 72 pixels as the resolution of the texture.
