title: Detecting when error image in PictureBox is used
body: <p>I found this on Google, <a href="http://social.msdn.microsoft.com/Forums/en/vbgeneral/thread/55840495-421a-4885-9d27-1dd04fabdcb3" rel="noreferrer">click here</a>, which someone asked a similar question, receiving a response that they should check if their file exists. However, I'm loading images from <em>web links</em>, in which it displays an error image if A)The picture is not found or B)If, like in image hosting services like Photobucket, displays the 'Bandwidth exceeded' image. Is there a way to detect if either an error image is showing or if a image is invalid?</p>
