Here are two web applications for sharing photos and images. Both of them are free!
Â Flickr (www.flickr.com)
Â BubbleShare (www.bubbleshare.com)
This resource is similar to Flickr but also includes the ability to record up to 30 seconds of audio for each image. Remember images do not have to be photographs. They could be PowerPoint slides that have been saved as individual images. Upload the slides and incorporate audio for a web based presentation.
Remember, these resources are open to everyone and even though a slide show you create may be private (meaning only those individuals you send an email to can view them), your slide show may lead a viewer back to the sites (Flicker, BubbleShare)Â main page, and there may be images not related to what you are teaching on their front page.
