I took a look at your page and I don't see our Fotomoto Script when I view the HTML source for your page, so it looks like the Fotomoto plugin either isn't installed or configured correctly as explained here.
Could you please go to your WordPress Dashboard and
a) make sure the plugin is installed and active
b) has your Site Key in Settings > Fotomoto and
c) that the correct items are enabled under the Pages and Categories tabs in Settings > Fotomoto
Also, please make sure that any updates to the plugin are installed.
I hope that helps and kind regards,
We haven't heard back from you on this, and I am still not seeing the Fotomoto Script appearing in the source HTML for your page, so if you're still wanting to use Fotomoto to sell your images, please follow the steps above or re-trace the steps in How do I install Fotomoto on WordPress? to make sure everything is set up correctly.
I'm going to go ahead and mark this post "resolved", but if you need further assistance, feel free to post again or send us an email and we'll be glad to assist you.
