We have a lot of documents in our folders and there is no need to generate tiny images as it is really slow and pins all 16 cores to 100% as users scroll.
We want to keep this feature for Image thumbnails (png, jpg). I just can’t figure out how to do this…
I know we can pre-generate thumbs, but I don’t want the user to need to load the images at all. The default icons are far better
This disables PDF but also everything else:
'enable_previews' => false
This disables images but PDF and other documents still generates thumbnails:
'enabledPreviewProviders' => 
I’ve gone as far as to edit ImageMagic’s meta.xml and removed PDF from the meta and it still generates thumbnails.
How do I disable document thumbnails? Ripping my hair out here
