Shutter

Shutter is a feature-rich screenshot program.

I was trying to take screenshots of a whole web page. Shutter says it cannot take screenshots of a web page until gnome-web-photo is installed.

I installed gnome-web-photo and Shutter still can’t take screenshots of web pages, but I can use gnome-web-photo to do that now:
