Trailing images effect except images are pushed down by layers on top. HELP!

Hi guys ive added this trailing image effect. However what ive noticed is, the more elements you put on top of the section including the trailing images, the more it gets pushed down

(i thought the effect wasnt working but infact because there was many large layers including a background video on top, the images got pushed out of site)

i believe this is an issue in the custom code which i got from a youtube video

ive attached screenshots to demonstrate what i mean. how can i fix this issue and fix the code so i can add layers on top?

in the screenshots ive provided, the red dot indicates where my cursor is
