Less images more CSS

If you are creating your website from a scratch, try to have only few images, use CSS instead and if you need to have images, allways use tags to tell spiders what picture is about, because they can't read images, so they need some kind of explanation, this what image alts are for.
Don't try to put to much keywords in image alts , this is bad try to keep keyword density in image alts on one page between 2-6% at max.

i never thought of this one, im glad that i join this site, i learned a lot since im starting with my new domain hosted at godaddy. thanks for this helpful tip.

I did not quite understand the reason. Aren't images more alluring? Or did I not understand what were you trying to saying. What are image alts?
