Uploading images into separate directories for every new content My page, created using Drupal 7, will contain multiple galleries. I created new "Content Type" - "gallery" with an unlimited numer of "Image" fields. For each content of this type I want all of its images to be placed under different directory, eg. sites/default/files/gallery_01, sites/default/files/gallery_02, etc.

There is a "File directory" setting but I don't know how to make it content-dependent (when I create new content I want all uploaded images to be placed in a different directory).

Is there any way I can accomplish this ?
Why you would want to do that, I don't know. However, you can use Filefield Paths module with tokens. If you use the timestamp token you can have each directory created named based on timestamp. That will make them unique.
