The slow fading isn't a problem,

What are problems is the lack of viable alt attributes describing each
image. Also the inability to turn it off and on again is also problematic
with accessibility.

Subject: [WebAIM] CSS Photo Shuffler Accessibility

Any opinions on the accessibility of Carl Camera's "CSS Photo Shuffler":

http://iamacamera.org/sandbox/photoshuffler/

We are contemplating using something like this on one of our sites.

It doesn't seem to flicker or produce a strobe-like affect. But is the slow
fading affect a problem?

Our University standard [1] says to:

"Avoid the use of blinking page elements and scrolling marquees.
Blinking page elements and the refreshing of the screen to animate marquees
shall do so at a frequency of less than twice a second (2 Hz) or greater
than 55 times a second (55 Hz)."

Also is the lack of an on/off switch that the _user_ could control...with
_off_ as the default a problem? Any other problems with it?

Thanks,
Laura
