Force download image with .htaccess

I have a few images I have for download. The text links to the images are placed in a text editor block. In the link dialog in the tab «advanced settings» I tick «force download».

that works well on a stage site. But when online, .htaccess enabled, the image shows in the browser window.

What needs to go into the .htaccess file?

or something else?

I want to force the download of the images.

Thanks for help.

In theory this is valid for .jpg files

<FilesMatch "\.(?i:jpg)$">
ForceType application/octet-stream
Header set Content-Disposition attachment

I used something like this for .pdf files, but I didn’t try it for images.

Thanks, that is the right setting, - one can even pipe it with other file formats.
