They are all jewed. That's why I added an expando fallback (poal mirror) when you share a pic8 link.
Okay, I took all new pictures, again. Only one of them is over 3mp. When I try to make an album only one picture goes in, the biggest one. So I uploaded them all individually and they all went just fine. https://poal.co/s/3dprinting/755791So this is how I posted them. Oh well, not as nice but it worked.
The issue could be with pic8 hosts that have image size limit.
An updated function that would detect a server response and switch to another host could fix it.
That sounds like a good idea.
