Another thing you can do is go to the Material
Room and change the U_scale and the V_scale
setting in the Image Map box. The default is
1.000 for each. A smaller number makes the image
smaller. A larger number makes the image larger.
This saves the trouble of having to make different
size jpeg files. Use the U_offset to move the
image left or right and the V_offset to move the
image up or down. If you want an single image
set Image_Mapped to None instead of Tile.
Using this I can apply a large picture to a small
object or a small picture to a large object
without having to rescale the picture in a paint
program.
