In some ways, it has always been optional. In the bad old days, we made it "mandatory" primarily because it caused the browsers to load the images much faster. Under HTML5, you will find that the size is omitted unless you want to display the image at a different size than the actual image size. They even have other attributes to indicate usage of the actual size of the image called naturalWidth and naturalHeight. This goes back to the whole html5 concept of KISS, be specific only when you need to be and be specific when you need to convey information. > >> >> (d) apparently enforced alt text, inserted even if I delete it. >>> >>> I also would prefer deleting would result in an empty alt attribute, >>> but I did find that if you enter a space, that works to make it " " >> >> All text is REQUIRED on all images.
