Reloading the image dropdown add-on solved the problem. I was still running version 2.3 now I have 2.8 it seems not to automatically update.
One thing that changed is the background color of the ImageDropDown addon select box, it is now transparent all the other boxes are white. How can I change the background color of this box to white
How can I change the background color of the other PPOM boxes to transparent because this transparant looks actually nice too.
