Create Artist: Images are rendering out of order

[ryandeshon]

As an artist, I would like my primary image to actually be my first image, so when I use my promote image its is using the correct one.

Steps to reproduce:

1. Create/Edit an artist page and upload 3 images.
2. Save artist page.
3. Return to Edit artist page and change the primary image.
4. Save artist page.
5. Observe the image on the FE is not the Primary image that was selected.
6. Observe the Primary Image is not being used for the promote page images.

Dev note:
Images use an 'order' that is supposed to be saved, but the FE seems to be ignoring it. Not sure if its not saving on the BE or that the FE doesn't care. I (Ryan) can't reproduce locally.

I have this issue on my live artist page: https://www.ampled.com/artist/theargentgrub
if you need a live example.
I don't have a development environment set up yet to test.
I have removed, reloaded etc but the order is not as I'd wish
