Mapped Network Drive Problem

This is fundamentally an HTML problem, but is here since it involves scripting, please let me know if that would be a better forum for this problem.

I recently created a page on our local network that uses PHP to access a mapped network drive in order to create web galleries of images there. My problem is that I haven't been able to figure out how to display the images. I can't just do something like this:

<img src="Z:\images\22000.jpg" ....

Because that won't work, of course. It also doesn't seem to work if I do this:
<img src="fileserver//images/22000.jpg"...

I've also tried a lot of variations of each.

Regarding permissions: Incidentally, the second version of this simply causes the page to be stuck loading. The server (apache 2) has permission to access the drive- I can use PHP to get directory listings, access db files, etc. on the drive.

Is what I'm trying to do clear? Any help provided would be greatly appreciated, as I don't have much time to make this work. (Isn't that always the way? )

aaaa...
i think it's better that you copy images in a folder in your site root folder.
such as :
it is your web : \index.php
make a folder near it ! and copy images in it and resource images in this folder
\images\*.jpg
<img src="/images/abcd.jpg".....
can it help you ?
