I am having some problems with images in trying to load RLWorld.py .  It may be noteworthy that the image on the curriculum pages dealing with RL also does not appear on the web page.

Thanks for your help on this
Christine

Christine,

This looks like the same issue you reported a few months ago (right?), 
to which I replied:

There were some corrupted images when we migrated from CVS to SVN, but 
those have been fixed thanks to Debbie Burhans.

You can get those images from:

http://svn.cs.brynmawr.edu/viewvc/pyrobot/trunk/images/

Click each image link, and then (download) saving (as root) into 
/usr/local/pyrobot/images/.

-Doug
