[etoys-dev] remove the free-standing .gif?

EtoysIllinois is not a swiki but rather a site designed so I/we could tag and add projects easily. Michael McKelvey, at MSTE/UIUC, designed the site and he can tell you much more. 

If the only reason for this proposed change is that some children some times select the .gif instead of the .pr, I would not spend any more time on this and would not make any change. Children learn quickly that a .gif is a picture and .pr is a lot more fun.
