Images fail to load in ContactMonkey when your web security tools (firewall or antivirus software) block the URL where ContactMonkey hosts image files. This causes images to appear as thin lines, disappear from templates, or show errors when accessing file links.

Quick Solutions to Try First
Try these steps before contacting your IT team:
- Clear your browser's cache and cookies
- Disable browser extensions temporarily
- Switch to a different browser (Edge, Chrome, or Firefox)
- Verify your computer's date and time settings are correct
Permanent Solution: Safelist the ContactMonkey URL
If quick solutions don't work, ask your IT or Security team to safelist (allow access to) the ContactMonkey URL for your region.
