Extracting textures form .3ds .obj Ect.

Does anyone know how to extrtact the textures from different formats?
I get a “members only freebies” from the 3D Studio, and you can download the models in several formats, which would be the easiest to exctract textures from?

The textures will likely be in seperate image files (.jpg, png) etc so it doesn’t matter what format you use the textures will just be images. The .obj or .3ds file will contain UV co-ords to map the texture and at best a path pointing to the image file names and relative path details.

If you have the choice, .obj is the better of the 2 formats you mentioned from a quality point of view of the mesh.
