My internet shop displays thumbnails of products' images, and I see that these thumbnail are (slowly) being indexed by Google. I want also full images to be indexed. (I've seen some other questions on that topic, but this one is not a duplicate I think).
So my question is:can I use microdata for this? Something like this:
<meta itemprop="image" content="/uploads/images/medium/product_img.jpg" />
<meta itemprop="image" src="/uploads/images/medium/product_img.jpg" />
Would it do the trick?
