Alvaro,
Let's say that you want to apply two textures, Ta and Tb to one or more
shapes. If the effect that you want is for Ta and Tb to be overlaid on
each other such that the texture coordinates for the two are always the
same and the sizes of Ta and Tb are the same, then combine them into a
single image and just use that.
However, multi-texturing gives you LOTS more. For instance, Ta could be a
texture which is animated across a ground plane (to simulate cloud cover),
while Tb could simply be your ground image (grass, dirt, etc.).
Oftentimes, people use multitexturing to actually decrease texture memory
usage while increasing overall image quality. For instance, if you have a
marble floor mosaic that is used in multiple places within your environment
but you want to use pre-rendered shadows on this texture, it would require
a different floor texture for each unique use. However, if you can share
the floor texture but provide a lower resolution 8-bit image (intensity
only) for the shadow effects you can save a great deal of texture memory.
