Fotopedia is a new combination photo-sharing and encyclopedia site.
You have to download software in order to upload your photos, so that part isn’t feasible for most schools. However, anybody can access the pages on the site, which combine user-contributed photos with excerpts from Wikipedia articles on the topic. It’s very accessible to English Language Learners, and it’s particularly engaging because anybody can vote on whether photos permanently become part of the site’s pages on the topic.
In some ways it’s similar to Navify, which also adds multimedia to Wikipedia text. However, once Fotopedia gets more content, I think it’ll be even better.
