I know for Google Shopping (or whatever it's called now) it's recommended providing the URL to the highest quality image there is for the product. Does that same principal apply for Product rich snippets?
Although it's rendered on the product page, I can easily provide the URL to the high-res image like this:
<meta itemprop="image" content="/img/high-res.jpg"></meta>
Or I can just tag itemprop="image"
to one of the lower quality images that is shown on the website? But it's only 400 x 400px, compared to high-res which is 2000 x 2000px.
Any thoughts?
