ANTIALIAS was removed in Pillow 10.0.0 (after being deprecated through many previous versions). Now you need to use PIL.Image.LANCZOS or PIL.Image.Resampling.LANCZOS. https://stackoverflow.com/a/76616129/5541592

Line 467 must be corrected. Even better, I presume, if a user can manage the compression type using some user-defined parameter.

Seems like this was fixed on the master branch (currently version 1.6.1),
https://github.com/flask-admin/flask-admin/blob/14e24c970f0ee3a29add830612eee9a0b0ba5dcc/flask_admin/form/upload.py#L464

And here is the commit 96b92de

I tested uploading a file, and didn't receive any errors.

Seems like this was fixed on the master branch (currently version 1.6.1),

Maybe I'm wrong but I can see the commit and this is from August 9, 2023:

And the version was released June 19:

So the fix was added two months later?

And another thing, I can see 1.6.1 being on a different date on pypi, February 20 (Which matches the tag build):

I just downloaded the source code that is attached to the release here on GH for 1.6.1 and still can see ANTIALIAS:

And I have got the error despite reinstalling the library a few times:

You're right - it looks like this change hasn't been released yet. This project has just been transferred under to the pallets ecosysytem project, so hopefully we can get a release lined up shortly, but we have some admin to take care of first.
