I am trying to create a favicon code for a web browser project, and I need to be able to make the code support when the application cannot find the favicon, crashes, and returns this error:

This is the full code I have for retrieving the favicon, and displaying it in a picturebox:
The bolded out part of the code is the part I attempted to use which obviously didn't work. As you can see, it isn't complete. Any help would be appreciated guys. Thanks.
