• Initialize an image server instance using parameters stored in a YAML configuration
• Retrieve resources managed by the server and demonstrate how to access object properties
• Retrieve a zip archive of DCM resources, list the contents, and upload images to Orthanc for indexing
• Show how to access a series, retrieve the DCM instances associated with it, fetch extended tag sets, and visualize image data
• Create a blog post covering the client examples
