Connect a Sketch is a free service intended to help people take their existing sketches and images and arrange them into an online flowchart. Creating a flowchart is just a matter of uploading JNP and or PNG images then arranging them into a sequence you want. You can then add connecting lines between your images. If you have a new element to add to your sequence you can go back and edit your sketch.

Applications for Education
Connect a Sketch was built for developing prototypes for industrial applications, but the service can just as easily be used for arranging any series of PNG and or JPG files into a sequence. Students could use Connect a Sketch to arrange images from news stories into a sequence, diagram a story they’re writing, or show the steps for solving a problem.
