One of my favorite smartphone photo apps is BeFunky, which I have on my Android. I was thrilled to discover there's a BeFunky Chrome extension to use with photos on your computer, or from flickr, or any other way you can access your photos via your computer. They also have a website you can use. Awesome! There's a premium service, but the free, basic service has a lot of features. Now I don't feel so bad that Picnik is gone. And I do still have Photoshop. But if you're looking for a free, easy-to-use online photo editor, especially to do effects, I recommend BeFunky.
