Yes, as of 2018 websites absolutely must be ADA compliant. Its a new but very scary issue that has flared up over the last year and is set to cause a LOT of turmoil. The Supreme court issued a judgement that opened up a loophole and opportunity-chasing lawyers are aggressively soliciting handicapped people and convincing them to sue unsuspecting website owners (pretty much every website owner on the planet, as not a single one of us were ADA compliant before now.)
Many web developers have already realized this too and are exploiting business owners for $3k-$20k to make their sites compliant because they have no choice. So we came up with an extremely low-cost solution so everyone can remove themselves from risk, have compliant websites, and immediately. My website iFuzeMarketing.com is compliant. Visit it, press the handicap widget at the top, and play with its simple functions. We can custom build and install one for anyone's website that's reading this. It will deliver all the same functions, and we'll code it into your site for you so you don't have to worry about this risk any longer. Everybody needs this. Feel free to contact me for details if interested.

The words in the tag should be more than a description. They should provide a text equivalent of the image. In other words, the tag should include the same meaningful information that other users obtain by looking at the image. In the example of the mayor’s picture, adding an “alt” tag with the words “Photograph of Mayor Jane Smith” provides a meaningful description.
