Hi there!

I’m using Gallery field in my website, and I didn’t unserstand: how I can change filenames for upload files?
I found a few topics about changing filename for one file, but in case of using Gallery I have any files.

Do you help me? Thanks a lot!

It works for one file or multiple files.

wp_handle_upload_prefilter run on every image.
