File type / Icon

I never "played" with icons, but I would like to have a same icon for all picture files, except gifs (another icon).
How could I proceed please?

More a Windows question than an Opus one.

What are the icons currently? Editing file types in Windows can be a pain, since the registry has so many places that override each other. Sometimes the default image viewer on your system lets you pick the icons it assigns. They come from there, ultimately.

Oh sorry, it was just some extensions (as jpeg) which were still with the Photos app (and its icon) from Windows 10 by default. Fixed now. Thanks again Leo :slight_smile:
