wait... what kind of painting you want to do? and this is just an image not a sprite.
if you think painting using sprite is asier pls study this tutorial because evrything that you should know about sprites are here
search for "IBM introduction to sprites" (you must register first though) but it is the simplest tutorial i know.
if you still want to stick with your painting method this is the pseudocode:
1. paint the background
2. clip the image
3. draw the image
4. unset the clipping
if you want to draw another (part of) image
5. clip gain
4. paint image
5. unset the clipping
and so forth....
so... clipping cosumes much hard coding but compared to sprites, clipping saves much memory heap... but i think sprites are sleaner to use.
