Biteslide is a web-based tool you can use to create slides and slideshows. Here’s an intro video:
You do need to register to use the site. If you register as a student, you need a registration code, which I can give you. Or, you can register as a teacher. When you’re finished creating your slides, you can present them on your device, download them as png files, or you can share the URL with your friends, but they have to be logged in to view from the URL.
I made this one about my “30 Day Challenge” — which turned into a 90 Day Challenge and I’m still going strong. The site is easy to use and would be great for making multi-media presentations, including images, text, and video.
