I have a wallpaper gallery page that displays small thumbnails, when clicked it opens the original full size image for a user to download it.
alt attribute to the thumbnails make the original full size photo appear in google images when searched for? or Google will show the small thumbnail photos? I do intend to achieve the first option.
<div class="thumb"> <a href="images/wallpaper.jpg"> <img src="images/wallpaper-small.jpg"> </a> </div>
