I have a gallery website, it contains categories and displays in each category thumbnails from pictures in that category (as you would have expect).
What do I need to do in order for Google to index the full size photo and not just the thumbnail?
If I use a lightbox plugin, I presume googleimagebot cannot index the full picture, correct? It will index just the thumbnail.
I could just link the full image but it is not appealing to the eye unfortunately.
What is the best approach in terms of SEO, so that google will index the full size picture but keep it nice for the user too?
