I installed your plugin and tested it (complete checkout) sometimes. I liked it and i started to translate it to Portuguese and trying to using it into my photo website.
But, i don't know why, the heading links of the secure-images, don't work anymore. I reinstalled the plugin and my theme but still not working. They return a 404 error when clicking them.
You can test it here:
Offtopic: please contact me if you want the portuguese translation php files.
