Can't see image in firefox using imageurl property

Hi, I am trying to load an image in my webpage from a file server where all of our images will be held.I set the imageurl property on the image control to dynamically;;

image1.ImageUrl =photo+"//"+image1.jpg;(Here photo is a string that value is: "//server/DBV/Documents/Employee/phot")

and I can see the image perfectly fine in IE.


However, the image does not show in Firefox. In Firefox it is just a blank screen when i am using developer tools that image button is in there but it showing faded in developer tool(firebug).in screen nothing showing only blank.

Any body please help me urgently?????

Thanks.
