<img src="http://www.sololearn.com/images/tree.jpg" alt="" /> Why the "alt"is added with img link? Plz ans
when a picture won't load alt shows a text you put there. it's a very effective for search engines to look for the right image.
It's simply the alternative that will be shown if the picture is not available.
alt attribute Stands for Alternate Text. It is used for Search engines as well as for Blind Peoples as they cannot see the image. They generally have a system that reads the alternate text for them, so that they can get idea about the image. Hope, this helps you..
it helps blind person to recognise what that image is https://www.sololearn.com/discuss/534030/?ref=app
