I have a question :  
Look the webpage  
[http://imagevuex.inn.no/imagevue/?configfile=config10.ini](http://imagevuex.inn.no/imagevue/?configfile=config10.ini)  
In the gallery, when you pass the mouse over the thumbnails an image preview appears nicely.:geek: I am crazy about it.

How can do that ??? What is the name of this effect?  
Any idea ??  
1000 thanks
