If an image content is "unknown" a solution is to use WAI CG's
recommendation and create a missing attribute. See the Recommendations
regarding auto-generated alternative text: [1]

"We have reached the following consensus concerning "automatically
generated" alternative text:

In order to address both the validity and human generation concerns,
we do not oppose the creation of 'autogenerated' and 'missing'
attributes where either one of these could be used to make an image
that does not have any human-generated text alternatives valid. (Note:
It is important that this marker is not included in the alternative
text string itself.)"
