[LON-CAPA-users] uploaded files (in essay responses or elsewhere?)

[Ray Batchelor]

I am curious about having students upload files as part of their (essay...?) 
answer. 
e.g.
I would like them to submit graphs. (with or without an associated text 
entry).

I can see how to enable this, in essayresponse, but would like some info 
regarding the issues and options?

Do you restrict submissions to certain types of files e.g. gifs?
Is there, or can there be a restriction on file sizes?
What is to be avoided?

Thanks
Ray
