Import images after git clone
The stage_file_proxy module is what you're looking for.
You can configure this module to download images on the fly, i.e. as they're needed, or have your local environment serve them straight from your remote environment.
From the project page on d.o, the simplest install:
composer require drupal/stage_file_proxy
drush en stage_file_proxy
drush config-set stage_file_proxy.settings origin &quot;https://www.example.com&quot;

The module's INSTALL.md file goes into more detail about all of the module's options.
