Easy Media Transfer: my preferred option.
My students make a lot of media projects. I am always having them use their iPad to interview their grandparents, film commercials about the importance of recycling, act out scenes from books they've read, create photo stories, create their own iBooks, and much more. All of these projects require photos and videos and sometimes the file sizes can become extremely large.
If students are working together in a group and need to collaborate and share pictures or video clips in order to make their final project, they are sometimes unable to transfer the media by using email or iMessage (due to file size or video length restrictions). Another problem is how to get these final projects onto a computer since we block the students from syncing their school iPads with their personal iTunes.
The fast and easy solution is to use one of several cheap media transfer apps available in the AppStore. I'll give you a rundown of how these apps work (they are all identical) and then give you AppStore links to 3 of them so you can pick whichever you want or keep an eye out for a sale or freebie.
