What do you mean by prevent donwloading?

1. Disable right click on Image and save image?
2. Type URL in Address bar?
3. Copy from Temporaty Internet files folder?
4. Send Web Request to download the image?

Please let me know what you mean by prevent donwloading from above possibilities(there may be more than these)?

Try this to prevent leeching -

In web config -

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.web>
<httpHandlers>
<add verb="*" path="*.jpg" type="jpg, jpg"/>
</httpHandlers>
</system.web>
</configuration>

Class -:-

using System;
using System.Web;

public class jpg : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
string FileName = context.Server.MapPath(context.Request.FilePath);
if (context.Request.ServerVariables["HTTP_REFERER"] == null)
{
context.Response.ContentType = "image/JPEG";
context.Response.WriteFile("/no.jpg");
}
else
{
if (context.Request.ServerVariables["HTTP_REFERER"].IndexOf("mydomain.com") > 0)
{
context.Response.ContentType = "image/JPEG";
context.Response.WriteFile(FileName);
}
else
{
context.Response.ContentType = "image/JPEG";
context.Response.WriteFile("/no.jpg");
}
}
}

public bool IsReusable
{
get
{
return true;
}
}

}

If you stop disabling image downloading from the site - why have images in the first place. If you want to put images in an application, users can view the images and download by right clicking on the browser.

You can do one thing disable the right-click on mouse and show alert box


Put the following script in the head of your page:

<script language="Javascript">

am = "This function is disabled!";


bV  = parseInt(navigator.appVersion)


bNS = navigator.appName=="Netscape"


bIE = navigator.appName=="Microsoft Internet Explorer"

function nrc(e) {

   if (bNS && e.which > 1){

      alert(am)
      return false

   } else if (bIE && (event.button >1)) {

     alert(am)
     return false;

   }
}


document.onmousedown = nrc;

if (document.layers) window.captureEvents(Event.MOUSEDOWN);

if (bNS && bV<5) window.onmousedown = nrc;

</script>


Regards

Asif

If you use Forms authentication, deny the permission for Images folder to anonymous user.

Put Images under App_Data Folder. This will not allow images to be downloaded.
