I need to explore it further, but I especially like its feature that lets you search for images and videos off the web right inside the slide-show creation process. Except for the wonderful Bookr tool, which is still by far the easiest way to make an online slideshow, all the other sites on my list require that you open up a separate window to search for images in order to get their url address first before you “plug” it in. This feature just makes it easier for English Language Learners and everybody else to create their shows. And 280 Slides has far more “bells and whistles” than Bookr.
You have to register if you want 280 Slides to save your presentation, but the process is simple and quick.
Thanks to the Free Technology For Teachers blog for finding another great site.
