Hello!
You need to login to our site (Theme Joomla) in order to read the guide, once you are logged in then you can view the guide at:
http://www.themejoomla.com/view/setup-guides/index.htmlIt does not matter where you store the gallery images on your server, all that matters is how you reference them in the module settings... check answer number three below. Here your answers:
(1) a suffix for the module is for individual module styling - you don't need to fill this in...
(2) link to image = opens the gallery image / link to category = opens the category the image is in.
(3) check the gallery image URL (web address in the address bar) - open up a gallery image from the front end of your site and check the URL and write down the numbers after &cid. Fill that in....
Good luck and happy coding, send me your URL and I will have a look if you are still stuck!
