DESCRIPTION:
    This sample demonstrates how to use basic agent operations using image file input for the
    the Azure Agents service using a synchronous client.

USAGE:
    python sample_agents_image_input_file.py

    Before running the sample:

    pip install azure-ai-projects azure-identity

    Set these environment variables with your own values:
    1) PROJECT_ENDPOINT - The Azure AI Project endpoint, as found in the Overview 
                          page of your Azure AI Foundry portal.
    2) MODEL_DEPLOYMENT_NAME - The deployment name of the AI model, as found under the "Name" column in 
       the "Models + endpoints" tab in your Azure AI Foundry project.
