<p class="MsoNormal">Hi all,<o:p></o:p></p>

<p class="MsoNormal">I’m working with one of our eLearning specialists. They are trying to make their STATS 151 Blackboard course more accessible. In the past they were pasting screenshots of the formulas into the course, which isn’t at all accessible.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Now they are using the built-in Blackboard equations editor. The formula still goes in as a graphic, but the actual formula is placed into the alt text for that image. Below is an example, and I wonder if anyone familiar with Math can check
this to see if it would be considered accessible? I read in a few places that this method is acceptable.<o:p></o:p></p>
