ASP.NET Image control not displaying an image

Question

I am trying to display an image from "C:\temp". Here's the code:

string root = "C:\temp\";

string[] files = Directory.GetFiles(root);

foreach (string f in files)
{
    if (Path.GetFileName(f).Contains(user.WorkEmail))
    {
        img1.ImageUrl = root + Path.GetFileName(f);
    }
}

If an image is not found, I get a thumbnail with a red "X" - fine, as expected.

If an image is found, I get a thumbnail but no image gets loaded/displayed. When I right click the thumbnail and go 'Properties' it shows the correct filename.

You need to make this image part of the web site in order to display it properly. You need to use a relative URL:

img1.ImageUrl = '/App_Data/foo.jpg';

The image file cannot be located anywhere, when it is part of the web site a separate request is made to the server to fetch the image which is served by IIS. If you want to use image files located in a folder outside of your site root you will need to write a generic handler which will read the image contents, stream it to the response with correct content-type and then point the ImageUrl to this handler.

looks like you're creating strings of the form "C:\temp\myfile.jpg", right?

That's not a valid URL. your address needs to be either relative to your website's root (e.g. /content/myfile.jpg) or else it needs to include the protocol (e.g. file://c:\temp\myfile.jpg for local files or http://mysite.com/content/myfile.jpg for web access)

i had that problem and solved it ... you should give the image adres cut e.g:

www.yoursite.com/folder/image.jpg

Your image source should be = "folder/image.jpd" No need of root or website.
