Question about Alt Tags

[schoolboy]

is this a bad idea???

Probably one of the worst ideas ever...

You'd do well to do some research on ALT tags, how they dramatically enhance SEO, and how they contribute to VALIDATION.

Removing ALT tags is extremely foolish.

is seo search engine optimization?
if it is then do i really need alt tage that say things like img_home or logo
?

by removing them and leaving '' '' have i damaged the cart?

what is validation?

sorry for my stupidity but this is the closing stages of a very long build and i am so tired now.

thank you very much
