Script for pushing webcam photos into Drupal 10 using a REST API.

Attached below is a Bash shell script used to push photographs into Drupal 10.  We are running a time-lapse project with Drupal serving as the back-end repository.  Using Drupal's out-of-the-box REST services makes for an easy setup.  Multiple cameras can be quickly integrated, making a very scalable solution if you want to run a lot of cameras at once.    Drupal would actually make a pretty nice security cam dashboard with a little tweaking to this code.
