PowerPoint and Accessibility: Teachers' (legal) obligations under Section 508
Section 508 mandates, among other things, that computer and web content for students provided by institutions like CCSF comply with guidelines that allow disabled students to access that content. Guidelines include:
- Colors should have enough contrast to make text easily visible
- Colors should not be a primary means of conveying information (because of color-blindness)
- All pictures must have Alt tags
- Narration should display text readable by a screen reader at the same time as the sound broadcasts
Here's a detailed summary (on SlideShare.net):

Make sure your PowerPoint presentations are accessible and conform to 508 guidelines by checking them with the inexpensive LecShare program.
LecShare can also export your presentations to captioned Movies in QuickTime, or to Web pages that have a table of contents and text for your narration.
Saving PowerPoint in other web-friendly formats
From the Save As menu in PowerPoint (accessibile from the Office Button in the 2007 version), you have several choices that work well on the web if you don't have sound. If you do have narration, LecShare is your best choice.

Here's how to save in these other formats [PowerPoint Show]
Note that the .pps extension for a PowerPoint Show becomes .ppsx if you you save in native PowerPoint 2007 format. This format requires that the viewer has the 2007 version of the program, or the viewer. You can also save as the older, more widely compatible .pps format from the Save As menu in PowerPoint 2007.
