[Zope] size of image in LocalFS

[AM]

Hi,
I have a set of images in a LocalFS. I provide links to those images on 
another page and when a user clicks on those links a small window pops 
up that displays the image.
 Is it possible in anyway to figure out the size of the image in advance 
so that I can size the pop up window to be the same??

TIA
AM
