How to detect a 404 error when loading a poster image?

Hello, I am new to Roku development and I have the hang of loading images from my server into a poster.

The one thing I can't seem to figure out at the moment is if for whatever reason, the request for the image fails (404 or 500 or anything other than 200), how can I detect that and deal with it?

Anyone have a sample or suggestion?

Figured it out. I can just monitor the state on the poster using myposter.observefield("state","myfunction") and it tells me loading, ready, failed.
