Perhaps it's only a newcomer mistake, but why texture maps (I mean
bitmap ones, not procedural) don't stay the same when I choose to
render at a higher resolution? I placed a black & yellow stripe (like
those "under construction") on a sliding panel, scaled the texture
until looked fine, rendered at 320x200. Not bad. Then rendered again
at 640x400 and the texture was a mess! Does render size affect texture
scaling? The model are the same size, just the render window is
bigger. What's wrong? Anyone knows?

Can you explain what kind of "mess" is happening.
Is your black&yellow line becoming crooked, or
the color is wrong or ... ?
Are you using anti-aliasing when you render the
bigger image. Turning it on can clean up a lot of
problems with strait lines that are at an angle to
the camera.
Try 640x480 AA 0.3 or even 640x480 AA 0.1
and see if that helps.

Make sure you use "interpolate 2" in the
image_map statement -- it smooths out the
transition between raster file pixels.
