Accessibility Issues -- part 2

I'm working to get "alt tags" on the photos here, but sometimes it's hard to tell if they are working. At the moment, I'm using http://webaim.org/ to help me see where I need to edit my text or pictures to be usable by folks with vision issues. WebAIM provides a free "checker" at http://wave.webaim.org/ which scans a site for possible road blocks and provides information about them. Going forward, I'll use it to scan my new blogs and repair them. As time allows, I will also check my earlier posts for obstructive errors.
