Hello friends,

Why do we use alt text on images?

In case our image no longer exist or visitor has image loading disabled (to reduce internet data transfer) he can see your alt text and it can tell him alot.

<img src="/images/image.jpg" alt="image of me" />

When browsers are not able to load images properly they display the text that one has put in the alt text field. The text can consist of a word or a sentence that defines the image. Some the software would read the text for visually impaired users.

The alt text is also displayed if there is an issue with displaying the image when the page renders.

I think alt tag represent your images to search engine.
