How to Optimize Images for Better Search Engine Rankings?

Yes chuck i know that but i need to ask When you see a picture of a baby crying, you instantly recognize what’s going on in the picture.

The problem is, this instant recognition isn’t possible for search engine spiders at this time. Instead, you must help the spiders understand each of your images with alt text.

What is image alt text?

Images are read from the Alt tags placed behind the photo

Can we add title and description in the alt tag liza?
and plz let me know what are the attributes of alt tag .

They only read alt tags. You just have to make sure you name your pictures using Alt tags.

yes abdul but my question is how search engines read our images i read somewhere that search engone do not know about images they can read images until and unless we hav an alt tag there....

Make it easy and understandable to people, Image = 1000 words to people if they understand what its mean.
