here’s an idea FOR MODIFICATION!!!111. one solid block of 150 containers containing all range of images should appear in a fixed and auto-fitted manner that will auto-fit on whole window. this code scanning some range in url for specific present images in range available. sometimes urls for images is empty, and this containers will be empty as well.
the gallery block should be solid as stone with all the images inside. need to strictly auto-fit that gallery block strictly only within window or viewport width and heigth. need also to make sure that asynch updating function normally implemented for each cell of images in whole entire grid, to be accurate and not overhead that backend and cause an attention.IDK what you do but they are geting out of viewport or window size and a scrollbar appears, while this whole gallery, except controls, shall stay within space available in all possible and impossible sides of browser window. the whole gallery shall scale down simply with all containing images, even to micro sizes, but stay strictly within space available!!!111111111111111111111 also, I think you forgot one thing "object-fit: scale-down"!:
