The BeFunky Photo Editor is a great online app for simple edits to photos. It's becoming one of my favorites due to the ease and speed of use, the intuitive nature of the left sidebar, and some import and sharing options. I should point out that BeFunky gets a high rating on its Android and IOS apps.
Import:
You have the option of importing your photos from your computer, Facebook, previous BeFunky uploads, Flickr, Photobucket, and Picasa. The headline on the selection box says "Where's your photo at?", presumably placing the preposition at the end purposely for humor, or to sound homey.
Editing:
There are too many editing features to list here, my recommendation (as always) would be to play with the application yourself to see just how powerful it is. You get all the common editing features, plus some amazing filters, artistic renderings, frames, text features, and a large sticker selection, labeled "goodies."
Sharing:
Once you are finished editing your photo, you get some great sharing options as well. You can create a BeFunky account, and start your own photo stream there. You can also save it to your computer, and share on Facebook, Twitter, Tumblr, and Flickr. THE BEAUTIFUL thing about this sharing option is that you can, in one click share to all of these services, or just some of them, just by flipping the "Yep/Nope" switch on each sharing service.
For educational purposes it is definitely worth using from a couple of standpoints. First, it encourages creativity in students by letting them "play in the sandbox", just to see "what would it look like if..." It is also valuable to show them (and point out) how well put together the app is. Since anyone can publish whatever they like online, there are some apps that were good ideas to start with, but they just aren't well thought out enough to be useful. And of course, there are some apps that weren't even a good idea to start with.
BeFunky is a well-thought-out, good idea that can work for many different people for many different reasons, and for that reason, I believe that the word should be spread.
