Generating Random images from Directory

Hey guys, here's whats going on. I need to pull from a folder on our webserver and generate a random image based off of the images in that folder.
Using VS 2005 by the way.
Here's what I have:
--
Random RanNum = new Random();
string[] fileImages = Directory.GetFiles(MapPath(@".\Images\random\"));

RandomImage.ImageUrl = fileImages[RanNum.Next(fileImages.Length)];
--
This is my physical path to where the files are:
C:\Chris.Peele\My Documents\Visual Studio 2005\WebSites\HighSide\Images\random
RandomImage is the id of the <asp:Image> control.
It doesn't output the images just the little red X
When I view the page source in the browser or in the debugger it shows: <img url="C:\Chris.Peele\My Documents\Visual Studio 2005\WebSites\HighSide\Images\random\blah.gif">
I have no idea what is causing this but it has something to do with paths (I think).
Thanks guys!
Chris

Bassicly Random can give any value. Are you sure that you have 100546 file?

Setting the Image.ImageUrl should produce something like:

Note that the attribute is src not url for image location. I suspect it's a typo because VS 2005 Beta 2 produced code like the above for me.

The problem that you're experiencing is that src has to refer to a URL, not a file path. You can specify a file URL by prepending "file:///" (N.B. 3 slashes, not 2). This will only work if you're running locally. If you want to render a URL that will be accessible via HTTP, you'll want to generate the random picture as above, strip off the filename and then append it to ./Images/random/.

Thanks James! Would you mind showing me how I would alter the code below:
Random RanNum = new Random();
string[] fileImages = Directory.GetFiles(MapPath(@".\Images\random\"));

RandomImage.ImageUrl = fileImages[RanNum.Next(fileImages.Length)];

Thanks again!
Chris
