If there are greater than or equal to 4 photos, name 4 photos. If there are lower than 4 photos, name the primary picture or characteristic picture as thumbnail. If there is no such thing as a thumbnail, it’s best to not show it. To assist exterior linked footage.
like this. The archive checklist outputs a number of photos from the article it belongs to:
title
Picture 1. Picture 2, Picture 3, Picture 4
title
first picture (or featured picture)
…………
loop output
I’ve discovered a number of codes that solely meet a few of the wants. Learn how to mix these features, or there’s a higher means (perform code)
