First, sorry about to post a question.

The issue is that I'm not able to show local images via <img src="file:///path/to/someimage.jpg ....

I posted the question on Stack Overflow 9 days ago:

https://stackoverflow.com/questions/62741325/show-local-image-file-tmp-someimage-jpg (+50 bounty)

Is someone so kind to give me instructions about how can I show on electron window picture files from local storage.

Thanks!!

I'm having the same problem. I was able to use your workaround (converting image to base64), but a big problem for me is when trying to load a video file.

If the video file is big (~500mb) then converting to a base64 string will just take too long.

When loading a video/image (like: src="file:///path/to/video.mp4") the chrome console shows this error:

For blazor atleast, putting the video inside the wwwroot folder will allow it to load normally, but that isn't a real possibility for me.

@ctrl-alt-d @GregorBiswanger I think this is a bug

This is not a bug @IRHM - it's how Electron works (see, e.g., https://stackoverflow.com/questions/50272451/electron-js-images-from-local-file-system).

You will need to serve this file - i.e., just create an endpoint somewhere and this endpoint does the file system access. This way, your HTML code uses http -> communication with your ASP.NET server and then from this you load / transport the contents of the file from the local FS.
