Images not properly displayed when Netgear Armor is enabled.

This has happened to me in the recent 6 months - it's not an issue before I upgraded to firmware V1.2.2.24.

I first found that images from various websites are not shown when Netgear Armor is enabled.
It started to happen on shopping sites in Taiwan, and then I also found it happens to Facebook, Twitter, and Instagram.

After I disabled Netgear Armor, everything is going very well as usual - images from all websites are shown instantly.

I wonder if I need to configure anything to make it work if Netgear Armor is enabled?
