Alright, i have saved about 20 images in a database (Firebase) and each image has its own URL stored in a cloud spreadsheet Airtable.
Now when I call the column, it loads all 20 images simultaneously and does not display the images until after all the 20 images are loaded, which takes about 2-3 minutes for the operation to complete.
I want to initially call 5 images and then load another 5, when the scroll handler extension detects a VTouchdown.
