When reordering images within the property editor, you may find that the images are not saving to the order you would like them to. This is because the ‘Updated’ pop up has not been triggered manually.
The images will only save in the order you have selected if the pop up below has been generated after each move.
To ensure you get this pop up, when you move an image into the desired location, make a small amendment in the ‘Image Name (alt text)’ Field, below each image. This can be as simple as hitting the spacebar on you keyboard and clicking off the image. Or alternatively, you can, once moved, add a text. As long as there is an edit the the field below each image you have moved, it will trigger the pop up box and ensure it will hold it’s position.
Now all that’s left is to remember to press ‘Save and Close’ to save your edit.
