Sprites have stoped working in v4.x, although Dan has a solution.

How is a sprite different from a just a picture?

With sprites, animation is easier. They don't erase the background when they move. You can also set a depth to them, so they can be part of the background or actual moving figures.

yes but as Tony said, they got rid of sprites in the newer versions of Turing. there is a substitue though... DanSprite (Tony posted a link above) there are a few other files as well, but DanSprite is to be used with offscreenonly while osme other are not. However, DanSprite does have a few bugs (as i found out when i tried to use it). I was pretty sure that he was to busy to update it more so i decided to make my own, and when i finish most of the little details i will be submitting it into the tutorials section with a description on how to use. hmm.. which reminds me maybe i should do more
