Models without .jpg, .bmp

[PredaNoob]

I'm downloaded a couple of 3d models to test out. However I noticed they don't come with the textures required to paint them. And when I render them they are without any texture (with the exception of .x files)
Is there any way to obtain the textures?

Have you checked the guts of the model files to see if the texture files are listed, and if they are, are they listed with a path appropriate to the path of the model itself. For specific answers, you would have to say what sort of file they are (e.g., obj). Some formats may have the textures archived within the file but many don't. I'm guessing your x files work because they came with textures and a path that points to the same directory your x file is in. That isn't automatically the case though.
