I want to make this, but i don’t now if its possible with the actual features:
I have a thousands of posts with featured images but without first image (before first paragraph) and another thousands with both.
So, homogenize, i want to find all posts without the first image before the first paragraph and import from the featured image and insert into this (before the first paragraph). With this, finally i don’t need to make some trash scripting in my theme to homogeneize this via code (everyone post will have first image + featured image).
Another solution is to remove first image before the first paragraph (i believe i saw this option on Quick Feaured Image), so finally the entire database post are homogeneus with all posts with featured image and not first image, but i don’t know if its a good practise in WP or i will need to have Featured Image + the same first image in post.
