Re: Question about animated images and ARIA

It could either be an alert [1], or a status indicator [2], or a 
progressbar [3], although I have misgivings for alert.

Alert is an "assertive" live region, and that may not apply to this 
situation.  I can't tell from your description.  Status, a "polite" live 
region, is another possibility.

Even so, an alert generally appears as a one-time event.  The situation 
you describe has a duration, and should involve "aria-busy" [4].  You 
could use an alert at the end of the loading operation to signal to the 
user that it has completed.

Progressbar, another "polite" live region that supports "aria-busy", is 
the best choice:
- "An element that displays the progress status for tasks that take a 
long time."
- "If the progressbar is describing the loading progress of a particular 
region of a page, ... set the aria-busy attribute to true on the region 
until it is finished loading."

Also, a progressbar can be indeterminate, and that seems to apply 
here.   Visually, indeterminate progressbars can be rendered in any 
number of ways including a bar with an animated stripe ("barber pole"), 
a spinning beach ball, a watch, an hour glass, and so on.  That sounds 
like what you describe, i.e., "an animated gif".
