The alt tag is an HTML attribute and it is used to provide the alternative to the images. Because, Most of the SE crawlers don't able to read the images and don't index them in their database, so, alt tag is used to provide the text alternative to the images, so, search engines crawlers will easily understand the image what is it about.

Alt tag used to describe what is there on the image and what is the function of the image. Those are used in the HTML code. The main purpose of the alt tag is to help the visually imperfect people who can read an alt attribute to better understand an on-page image.

If image fail to run that time alt tag is loaded. Alt tag helps web crawler to index the images properly. It helps to improve the implicit and explicit SEO.
