It's a good idea. Obviously you can't preemptively OCR all images but having "context menu -> follow link" which works on QR codes and images with links in them seems totally doable do me

I think that a separate program might be better, which could be used with any video source in any program, including a QR code made up from multiple pictures or from CSS, or a video, etc. Furthermore, it is not necessarily a URL.

However, it might also be made as a browser extension in case you do not want to use a separate program, or if you want to be able to follow such links directly without going through another program.
