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.Will adding 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>
alt attribute for thumbnail image that links to the original file
seo;html;alt attribute;thumbnail
