collison detecton with sprites

[diablo]

hi
i wanted to make a side-scrolling space invaders-like game.
i have my ship coded to fire on my enemies(well the enemies themselves r a different set of problems(cant get the ship and sprite to stay on one screen))
can you provide some code to help with collision detection of a sprite(jpeg format) thats 16(w)x32(h)pixels?
