Hi dinamiko,
many thanks for the recommendation about the page loading speed.
this little change in the single.php helped a lot!!! GREAT
I will have a look on my new pictures to upload them in a lower resolution now.
maybe I try to explain my issue with these two pages:
correct images shown as thumbnails in the bottom area: https://tobiasnikolafotografie.de/servus-muenchen/
images added directly after the text: https://tobiasnikolafotografie.de/die-gruene-insel/
post 1 is an old blog entry. here I deleted the pictures directly from underneath the text and after this they were shown as thumbnails.
post 2 is new. I’ve tried the same but I can only add the pictures after the text and not as you mentioned “FullFolio doesn’t implement a gallery, to show images in a post, upload images via Add media but not insert in the post., just save the post.”
I hope this was a better description as in my first try ??
Best Regards
Tobias
