How to display image stored on the network in asp.net (c#)

How to display image stored on the network in asp.net (using c#). I want img src to be the one given below:

\\pgapp\folder\image.jpg, where pgapp is the shared drive on the network.

I am using these codes but its not displaying the image on the webpage.

originalImage2.ImageUrl=@"\\pgapp\folder\image.jpg";

or

originalImage2.Attributes["src"]=ResolveUrl(@"\\pgapp\folder\image.jpg");

<div ID="imgContainer" runat="server" style="width: 400px; height: 400px;  overflow:auto; border: solid 1px black;
                    padding: 10px; margin-bottom: 5px;" >

If you want to display images which are store in the network path then change below setting in IIS,

  1. Navigate to IIS.
  2. Navigate to website in Sites folder.
  3. Select application website and navigate to right side Actions menu and click on View Virtual Directories. enter image description here
  4. Click on Add Virtual Directories and specify an alias as "images" and physical path as "network drive path". enter image description here enter image description here
  5. Test settings and Save it.
  6. Refresh application pool and test whether image is rendering or not.

To display images stored on a network in a users web browser do something like the following:

Convert the image to it's base64 counterpart and display:

// PhotoId is the network file path and name.
string photoId = "\\Photos\2015-May\390828d1-8f20-4fe9-9287-13d03894e9c0.jpg"

// Call to display the networked images.
lbl_images.Text += "<img src='" + this.PhotoBase64ImgSrc(photoId) + "' height='60px' width='60px' alt='photo' />";

// Supporting function that converts an image to base64.
protected string PhotoBase64ImgSrc(string fileNameandPath)
{
    byte[] byteArray = File.ReadAllBytes(fileNameandPath);
    string base64 = Convert.ToBase64String(byteArray);

    return string.Format("data:image/gif;base64,{0}", base64);
}

You will hit 2 problems:

  • Browsers normally can't access server shares (unless it is on the same network). You need to expose image through your site somehow so it visible like http://myserver/image/image1.jpg
  • "NTLM one hop" - your server will not be able to read files from remote server if you start rendering image through your server. You just need to verify if you have the problem and read about it.
