Hi, thanks both.
The problem was that i was using this javascript library
http://www.netzgesta.de/reflex/ with that image and the reflection
script was modifing the image widget html generated by gwt.
On the other hand i'm using a label because i'm building a gwt-apple-
like-dock so the simple title of an image wasn't be usefull for me.
