Answer 1

Using gsutil and its setmeta command:

gsutil -m setmeta -h "Content-Type:image/jpeg" gs://YOUR_BUCKET/**/*.jpg

Use the -m to activate a parallel update, in case you have a lot of objects.

The /**/* pattern will perform a recursive search on any folders that you may have on your bucket.

This only covers objects without forward slash characters in the name. If you also want to operate on objects named like picture/in/some/folder.jpg, then you should use a recursive glob pattern: gs://YOUR_BUCKET/**/*.jpg – Calbert

Thanks @Calbert ! I'll add it to my answer. – Nutriment
