Pics open in a Slider

Hello, I am using the sydney pro theme. I have a lot of pictures on my site, created like in the demo style. When I click on one pictures it opens the single picture created in the projects. Like in the demo version. I would like the picture to be opened in a new slider of this category (interior or holiday, etc.) Plus to have the option from there (slider) to go back to the category. In other words is it possible to use a slider that is related to the pictures of the category?
Is that possible? www.tomjasny-hotels.com.
Thanks so much,
Tom

Dear Tom,

Thank you for posting in. Apologies, such that objective isn’t supported either by the theme’s or the Sydney Portfolio plugin’s core.

As an alternative solution, you may use other portfolio plugin like the Portfolio Gallery or browse at WordPress.org or codecanyon.net.

Regards,
