Single popop menu attached to multiple images

I need to create a popup with items (small, medium, large) and attach
it to a whole bunch of images.
Its the same menus for all images. menus should popup around the point
on the image where it was
clicked.
can someone send me a little sample code to do this ?

do i have to create a new popup for my 100s of images ? or would i
create only one and
attach it to an event with x,y coordinates and popup the only one menu
there ?

Please help.

any code sample is highly appreciated.
