16.4.7.5 Weighing X01 Against a Secure Page Item

The X01 parameter is convenient, but not checksum-protected. Understand the potential risk of using this parameter to decide if a secure page item is more appropriate for your use case.

• Understanding Implications of Using X01
  Understand how an authenticated user can change the value of an image ID in the image URL using an image-serving page.
• Downloading Image with Secure Page Item
  When images are user-specific or sensitive, use a hidden page item instead of X01.
• Generating Image URL with Secure Item
  Generate checksum-protected image URLs by passing the image ID using the tamper-resistant page item name to get_url using its p_items and p_values parameters.
• Experiencing URL Checksum Protection
  Witness the URL tampering protection for image serving pages using a page item for the image ID.
