Pretty much as I asked in the title...
My site already has a fallback solution for featured images: it takes the first post image if no thumbnail is manually set.
I'm working on a big job, I should finally be close to finish it and, before installing, I'd like to know if there are known compatibility issues with this kind of function.
To make it perfectly clear, my goal is to have a featured image chosen as follows.
If I set one, use that one;
if I don't set one, but the post has (at least) a picture, use that picture;
if the post has no pics of any kind, use a default fallback image.
Will this work like that?
Thanks in advance for taking the time to answer. :)
