FileZilla is open source software, distributed free of charge under the terms of the GNU General Public License. It’s undoubtedly the most popular FTP program available.
GIMP– Photoshop is very expensive. Especially if you only need it to edit a few photos here and there. GIMP is a great free, open source version of Photoshop. The developers and maintainers of GIMP strive to be a high end free software graphics application for the editing and creation of original images, photos, icons, graphical elements of web pages and art for user interface elements. GIMP has tools used for image retouching and editing, free-form drawing, resizing, cropping, photo-montages, converting between different image formats, and more specialized tasks. Animated images such as GIF and MPEG files can be created using an animation plugin.
Dropbox– The super popular Dropbox is free cloud storage that can be accessed from anywhere with an internet connection. Store a copy of all of your important files (photos, website files, docs, etc.) in your Dropbox and access them from any computer or mobile device. Hint: Invaluable for backing up websites files and databases ; )
Google Analytics– Very in depth website hits/visitor tracking provided free of charge courtesy of Google. Just sign up for an account (or use your existing Google account) and install the code snippet they provide onto your website. Great for analyzing how much traffic you’re getting and where visitors are coming from.
