Pretty sure I've said this before, but alt text is brilliant for crossing cultural divides and telling me WTF is going on in pictures from contexts I have never seen before.
I don't expect anyone to recognise what a forestry skidder is for, no one expects me to know what a Wendy's is for. I don't expect anyone else to recognise an autoclave, no one excepts me to recognise a doorbell cam.
Ideal. No notes.
