Mixed Pricing test
Mixed pricing is enabled for this album. The bear image has an invalid pricing scheme and will throw an error. The forest sunrise image (cell 6) has no pricing scheme in the Category field and therefore uses the scheme entered for the album under the Integration tab in album set up.
For more on using Mixed Pricing, see this blog post. The final image has "not-for-sale" in the Category field and therefore there is no cart icon attached to the image.
