My lightbox order is still fucked with no explanation. put me in the ground.

I am deep in the hell of figuring out the lightbox function in my gallery. I want it to be in ascending order (newest first) so it's easer to add to, but the lightbox freaked out & now loads none of the images or the navigation arrows...

Does anyone know how to make "tabs" not all load/show at the start? I have the "active" tag on the only one I want to show but the code does not care

I return after 2 years, remembering why I walked away, I need to make the image gallery easier to upload to so I keep up with it...
