Edit: I got a comment here to use the RunWith addon. I create a shell script to open images in the preview app.
Sometimes on my Mac I want to open a image that could be opened in a new tab, directly into the Preview app (the default photo viewing app). It would be great if I could have a context menu option when right click images, to open them in the app, I wonder if there’s an addon to do this.
Not sure if this would work. Have you tried the Applications settings to open files by Photos?
Settings > Type “Applications” in search and associate JPEG to Photos app/default MAC App for pictures
The applications box doesn’t have a row for images.
I found this, try and see if it works: https://addons.mozilla.org/en-US/firefox/addon/external-application/
Thanks, though I went with the RunWith Addon. I do wish I took a look at this first, it might’ve taken less time to setup.
