Image gallery with click action to enlarge full screen

Hi all,

It’s my first request here, i hope that this suites correctly.
my data source in airtable is called “therapies”
I have another page called “attachments” in which, one video OR picture per row, i have either an url for the videos OR an attachment for the images.
Either case, there is a description along with the image or the video.
Every line in therapies is linked to one or more attachment lines.

I do have a page called “speech-therapies”, which is linked to therapies table - plus a filter to list only the speech one.

Then i have a detail page for the speech therapies.
In the detail page, i have managed to have a list of videos, and upon the click of one, it will open the video to play it as “modal view”.

I want to do the same, but i’m unable to make it happen.
I’m able to create another detail page just for the images, and then on another click it open the image, but it is “not what i desire” (read it as: a VERY BAD UX)

Is there a way to simply have a gallery that, upon click, will open full screen the images?

Thank you very much,
Daniel
