at one point i tried to add pickling support for Rect objects. i tried 
something with the __getstate__ functions, but it didn't end up working. 
(couldn't find docs on these). I'd definitely add them back in.

as for pickling images, it's a slightly different story since there is 
so much data. in python it is very easy to compress image data down to a 
reasonable size (although not the best size).

i wrote this code awhile ago that embeds an image into a .PY source 
file. it could easily be changed to send it to a pickle as a tuple of 4 
integers and strings. in fact, in a pickle the image would not need to 
be base64 encoded, so it would end up smaller.

it seems what you'd really want is to just save an image filename 
though. if you have many sprites referencing the same images it would 
get embedded many times. and what about sprites that use many images for 
animation?


oh, and someone asked about the UserRect, it got moved to the code 
repository awhile back (it turns out you're not insane, heh)
