Add photoswipe into this template

Hi,
Is there a way to add Photowsipe into this template, like it now comes with the original code of Quark, Hotel templates.
If not, is there any plan from our development team to add Photoswipe as a complement into our Steak House template in the future updates?
Thank you!

Steak House will not receive any new functionalities that are not there. We support templates by bugfixing or just updating support for most current Joomla.
If it goes to copying some finctionality from one template to another - it can be done by any skilled frontend developer.

Hi Cyberek,
Thanks for your responding.
Can you give some clues to help me do it myself? I can make some simple css, php modifications, but I am totally not a developer. Really need help in which files should be copied, which files need to modified...
Of course, you don't have to answer if it's out of supporting duty.
Thanks again!

Sorry but this kind of customisations are beyond our technical support. I might advice to search for a frontend developer for this custom job.
