select an image area on mouseover

[altalest]

Hi everyone :)

I would like the users on my website to be able to select the area they want from an image, by holding the click and moving the cursor.
(I mean like in Windows XP when you want to select numerous folders and that blue square appears depending on where you move the cursor; except that here the square would appear on a part of an image).

Moreover I'd like the area selected to stay over my image after it's done, and later be able to reset the process (thus emptying the whole image from its squares).

I hope it's clear, I don't know really how to explain. ;)
I guess this is possible with javascript, but since I know nothing about it, I'm posting on this forum ! :)

Thanx a lot for your help :)
Cheers

Actually not, unfortunately :/
But this is easy to understand, in the end : that is like when you select numerous folders on Windows XP and that draws a blue square :)
Do you get me? :)
