I remember being a big fan of Shutter, though some time ago, I switched to ScreenCloud ( https://screencloud.net/ ), for its ease in automatic instantly sharing.

Shutter works well with my common workflows. It lets me grab a screen area, adjusting the captured area on the fly BEFORE capturing, then saves the capture to a file, lets me launch its editor with a single click to do basic stuff like drawing lines, circles, and labels, then lets me copy the finished image to the clipboard.

Can't recommend Shutter enough; it's great!

It can take a website (gnome-web-photo), full screen or only partial shots; can edit them and has a few handy plugins (censor, pixelise, text etc), can upload to all sorts of image hosting sites including your own FTP and can use the Gnome gvfs, too.

I use shutter heavily, and have been doing for years - recommended.

Shutter is fantastic, has a bunch of dependencies but it's actually good.
