I, a wandering swordsman, routinely crop photos printed from Firefox and Thunderbird with my twin swords of super steel.
(My picture is to the left.) One day I decided there must be a better way than bandishing my sword every time a printout random encounters me.
Not everyone is a great swordsman like I am, able to wield bold precision that cuts needle-hairs in half. Thus I started developing this extension which automates a lot of the intermediate steps for importing photos to F-Spot from the aforementioned apps.
F-Spot is a photo management program similar to Apple's iPhoto or Google's Picasa. It has the basic tools that people who own a digital camera and a Linux box really should have to edit, manage, and export photos. Cropping photos with a bent butter knife of rust is not something that should be done.
You don't have to be a programmer to help! Among other things that can be done is translating. First download the Firefox or Thunderbird English localization files. Unzip them. Open the enclosed ".dtd" and ".properties" files with your text editor of choice (ex gedit, kate, vi, emacs...) and start translating! You can email me the changes at the bottom of the page and I will include it in the next update. Some examples of changes are below.
*.dtd files:To the brave, I salute you fiercely. The code is GPL. The files are xul, javascript, and css. I shall bestoy on you the basic development process. (The lines prefixed with "$" are terminal commands.)
