post thumbnails – Why are image sizes not being generated?
My WordPress is not generating thumbnails – or maybe it is… ?
I am seeing it create:
- the uploaded original, as added.
- a -scaled.ext file.
- one other smaller-scale size, image-name-1568xNNNN.jpeg…
I note that the 1568 is found within the Twenty Twenty One Theme’s functions.php, as
set_post_thumbnail_size( 1568, 9999 ); This size is only created when Twenty Twenty One Theme is active.
When Twenty Twenty Three is active, it is not created, only -scaled.ext is.
Shouldn’y I be expecting more, including the 150×150 thumbnail size?
It’s like these Media Settings are being ignored and sizing-down only happens if set in code.
A few months ago, I did go through a big process of media slim-down due to excess numbers of these alt-sizes images, and took steps to stop it happening, including setting the medium and large size dimensions to 0. But now I need to check that this process can actually work…
- I have disabled many media-related plugins.
- I don’t believe I have any code anywhere
unsetting size creation.
- The problem is despite sizes being set in Media Settings.
I am running this on MAMP locally, which says GD2 is installed. This often appears as a cause.
It’s not generating any more than the -scaled.ext and one other for both new images and any images on which I run Regenerate Thumbnails (which is currently disabled).
