Hi Bruce,
Derek from Fotomoto just chiming in here =). Fotomoto compatibility with this and any other theme will depend on how what it uses for an image gallery library. Fotomoto works with several libraries out-of-the-box, but there are hundreds if not thousands of libraries out there.
The point is that our JavaScript needs to be able to detect which image is the current one being viewed so that it can put the Buy links underneath.
If the theme developer would like to ensure that their theme is compatible, we’re happy to work with them and help promote their theme as compatible. If anyone needs to get in touch with us about this, they certainly can at https://support.fotomoto.com/customer/portal/emails/new.
I hope that helps!
Derek
