Upload and edit your own images. No account or login necessary. Great to combine with thinglink if you want to create an annotated collage of photos vs. just one image
"Canva is a nice tool for designing infographics, collages, flyers, and slides in your web browser or on your iPad. I've been a fan of the service since it launched. In fact, I like it so much that I became an unpaid advisor to them when they started thinking about developing resources specifically for teachers." ~ Richard Byrne
