[Request] Generation II Followers Sprites

Thanks for these sprites, DeathLord17! But I want to know how to make/get them myself. Since the sprites on the link below are in a vertical box, not facing in the same pattern as they should and they have a coloured background. For the Pokemon MMO, we need a horizontal box with no background(could be done with photoshop) and they face like: down; left; up; right.

Thanks in advance.
