People dont seem to like to talk about them here, i dont think anyone has actualy got them working.
At least, i have never seen any game use them.

I believe that this is what you are gonna need. It will load the needed texture. Place it at the top of your shader file.

texture ATextureName
<
string File = "filename.whatever";
string TextureType = "2D";
>;

I believe you will also have to set the sampler state for it as well, but a better example and explaination of what you will need can be found under Dark Basic Software\Dark Basic\Professional\Help\examples\basic3d\fx. There are a couple shaders there aniso, bubble, and simple, all of which load an image so they should be pretty good examples to learn from.

I'm kinda pressed for time at the moment so if you need any more help or clairification just post and I'll see if I can get to it later.
