image alt attribute

What is the alt attribute next to where the image details go? What does it do, and what should be the field? Why is it always a name - does it have to be the same as the name of the image?

It's a alternative to browsers that can't display an image and/or for disabled people. You write a description of what the image is. You can write anything you want.

Hi Violet,

The required alt attribute specifies an alternate text for an image, if the image cannot be displayed. The alt attribute provides alternative information for an image if a user for some reason cannot view it (because of slow connection, an error in the src attribute, or if the user uses a screen reader).

From w3schools

It does not have to be the same as the name of the image. Usually it will be more descriptive. I hope this helped.

So helpful, thank you!
