If you have a custom brand for your Zen Theme Foundation plugin, and upgraded the plugin from version 3 to 4.14. You might have noticed that some images are missing, or you might not even noticed them missing because no missing image is displayed.
To fix this, I just copied over the missing images from the Breeze template. Here is a list of them.
