CMS and Slider with multi-image field

I spent a lot of time looking for a solution to create a custom slider and I’m quite lost now.
The idea is to have a grid gallery with clicable thumbnails and custom navigation after the image comes to a “lightbox”.
Started with lightbox element and then tried with a slider element.
The idea is to use the CMS to show a lot of images inside each Portfolio page.


  • Slider with image index to clic on. Similar to this:
  • More than 25 images per Portfolio item.
  • Need to do it for +10 Portfolio pages so should be manageable.

I did manage to make it work with Cycle2 but now I’ve found the 25 items cap for each multi-image field.

Any ideas?
I have no problem to try custom code but I have no experience to create it.
