[Building Sakai] Equation images removed from answers in Samigo

[Daniel Merino]

Hi, Brian. Thanks for the clue but I have looked there and these classes 
are not related to our issue AFAIK.

There is some place between the form where questions are edited in 
Samigo and the class ItemAddListener.java where HTML is parsed and img 
tags are completely removed if their URL has some character that Samigo 
doesn't like.

Still looking for it without success. I wonder if it could be some 
javascript.

Any help will be highly appreciated as our teachers are losing their 
work when they edit it.

Best regards.
