Facebook gives hints about what a picture contains on the ‘alt’ field

Just a fun fact:

Facebook posts some of the information that it automatically derives from user pictures in the alt field of the pictures.
Below we post two samples from a stream that demonstrating this feature:

In the first one we can read in the alt the following Image may contain: 1 person, smiling, closeup.

In the second one we can read in the alt the following Image may contain: 1 person, sitting, pool, sky and outdoor.

We can see that in both cases the information is pretty much valid.
