How are you creating that portfolio section? With some plugin? If yes, please provide it’s name.
Also, don’t mark your topics as “not a support question” if you want help. “Non-support topics” don’t appear in the “Topics with no replies” list, and that reduces your chances to get any help, as volunteers actually look that list first 🙂
I use this theme at the moment, my excuse for marking. Hopefully you can help me further, my other question I am very curious about. thanks in advance

So, as you’re using a commercial product, we don’t have access to the theme code. The best way to get help is asking in it’s own support forums.
