Here’s the object debugger for one of the pages: http://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fwww.elon.edu%2Fe-net%2FNote.aspx%3Fid%3D954246

Notice the image box is empty, but when I click on it, the image opens just fine in every browser I could test. The image is served by an .ashx handler by asp.net with a content type of “image/jpeg”. Any ideas why Facebook doesn’t recognize any image served by my application? This causes all facebook posts to display without an image, which we want to avoid for aesthetic reasons. Thanks for any help!

    Look at the HTTP headers for the image and you’ll see that you’re sending a 404 HTTP status back with the image.

    telnet www.elon.edu 80

GET /e-net/Image.ashx?w=298&crop=true&id=28213 HTTP/1.1
HOST: www.elon.edu

    .

    HTTP/1.1 404 Not Found
Cache-Control: public, max-age=31536000
Content-Length: 14248
Content-Type: image/jpeg
X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727

    EDIT

    I don’t know if the 404 is causing the error but that’s where I’d start.

    EDIT2

    Based on your comments I’m guessing you’ve got something like this in your handler, right:

            try
        {
            //Logic here
            //..
            Response.End();
        }catch(Exception ex){

        }

    If so, your problem is Response.End() which actually throws a ThreadAbortException which is absolutely not what you were expecting probably. There’s a couple of different things you can do, I’ll let you read up on it and make your own choice.
