I have many images, and for a pretty view and better css control I mark them up as
<div style="background:url('image-url') no-repeat center center transparent; overflow:hidden; display:inline-block; width:150px; height:150px;"></div>
But as we know HTML allows adding
alt to image tags for search optimization. How can I include "alt text" in a background situation? I have submitted an image sitemap to Google, which includes all these image's URLs and page URLs.
