Jing for Uploading Picture Demonstration

I use Jing in order to demonstrate to my Yearbook students how to upload a picture they've saved to their desktop to our Pictavo website. Pictavo is the website we use to create our yearbook. Students are required to upload a total of approximately 12-10 pictures per week depending on how many pages they have been assigned to. I demonstrate in class how to upload but many times the students will forget and need to be refreshed on how to do it when the time actually comes.
