That further clarifies the difference but all of my alts are empty, i.e., there is not text.
As I mentioned to topr8, I usually introduce and follow the image with explanatory text so anything I put in the "alt" would be repetitive.
Not sure what to do about that. Actually, I'm not even sure when images wouldn't show.
It's all very interesting.
Thanks to everyone for the help on this. I have learned a lot through this thread.
