Welcome, always good to help new users along.

The pygame sprite classes do nothing with images really. You just assign 
them as attributes to the Sprite instances, and they get blitted as is.

I am guessing something is happening at load time. The main two 
questions are what image format are you using, and what type of 
transparency are you wanting: color key or alpha transparency?

If you have the right format, you should be able to just load the images 
and use them as is. That isn't always the most optimal, but it should 
just work.
