Dear all, 
user Alex Brollo has developed a very interesting tool which I think many of you will find very useful.
(afaiu he developed this from a previous tool, but he can explain it better)

To test it, go on your oldwikisource account, 
and in User:YOU/vector.js copy this:

importScript("User:Alex_brollo/cornersDependencies.js");
importScript("User:Alex brollo/corners.js");
importStylesheet("User:Alex brollo/common.css");
The tool will appear under Tools, and it's called "Ritaglio immagini" (crop images).
It opens a window which allows you to select and crop an image directy on the page. 
It is extremely useful to use illustration directly on the page.
It is usable both in View and Edit mode. 

In the Italian Wikisource we have made it a Gadget and button, so it's active for everyone.
