Unless you run adblockers and/or anti-tracking extensions in your browsers, you probably have no idea that any one of them can block your images from loading. Here's an example...

This image, filename adv_image-opt-min.png, is blocked by adblockers	This image, filename aio-min.png loads regardless of adblockers

Chances are you're seeing both images. But if you happen to be running adblockers such as Ghostery or uBlock Origin, the image on the left appears broken or missing.
