Local images and the browser widget

Thanks Mike, yes that does work for just displaying the image.

I’m building HTML on the fly and wanted to include the local image if there was one, for testing. This will be a moot point for production as everything will be served via a web server, but I was hoping to see this for testing.

I will be looking to the new http server LC has as I will need it anyway for doing some API things with this engine.

Thanks again to all!

Best,
Steve
