Why audio and video can like this but image cannot? (HTML5)

Question

<audio src…>text or anything that will show up if audio cannot be played</audio>
<video src…>text or anything that will show up if video cannot be played</video>

Why tf image cannot
<img src…>text or anything that will show up if audio cannot be played</img>
but must use alt…?

Thanks in advance for helping me

Answer 1

img is lineelement and didn't have end tag
<img src="link" alt="word that will appear if the image didn't appear to help user arrive to it by searching on google ">

Answer 2

Thank you. It is weird that audio and video are the same but they do image like that, it will be so perfect if everything is the same🤣

Answer 3

ALT text refers to invisible description of images which are read aloud to blind users on a screen reader. Adding ALT text allows authors to include images, but still provide the content in an alternative text based format.
