Image thumbnails are not appearing in an S3 bucket

Thumbnails are not appearing for images in an S3 bucket. Is there an Extra for this?

What version of MODX are you using?

Maybe try this:

Mate that normally happen if the uploaded file is too big, thy with a lighter file and see it it works.
What I saw using it is that S3 is very slow and it’s even worse with large images or too many images in one folder.
Not a god experience really!
