Can I create an image in another program like Photoshop and then import that into SU? I would like to create a logo elsewhere and then stick it on my SU model...

Can I draw basic shapes like rectangles and circles on curved surfaces? Basically I'm trying to create an effect like sticking a sticker on the side of a pole. (The sticker will have it's shape and that shape will stretch over the surface of the pole). Thanks a bunch for helping this 3 day old n00b
