Theme Horse

Anyway, as you will kindly visit the website, have a look at this issue I am not able to sort it out so far regarding the gallery:

http://www.gracianoempreendimentos.com.br/vendidos/colina-verde/

This is a link of an example of the gallery issue (my mistake probably) I can’t sort it out. If you click on the image, there’s no fancy gallery or nothing, just the link to the original page.

Could you please give a hint of how to do it properly?
Cheers.
