So do you always have to use "alt" at the end?

Question

<img src="link for img"/> will this not work ?

Answer 1

It will.
Although, alt is important, because sometimes, for different reasons, the image may not load. Also, I read somewhere that it also helps the visually impaired who are using readers.

Answer 2

The code will work. The reason why you should always use alt=" " at the end is because if the image is not loading, the alt=" " replaces the image that's supposed to be there with whatever you put in alt=" ".
