[7.2] Gradient not displaying in header, image display formatting absent.

Hello. I just ugraded my test server to 7.2 and it seems there's a few bugs in the header customization setup:

1. It doesn't appear to be displaying the gradient.

2. Custom images are squeezed to fit, or squeezed to fit if too large. They used to be centered and cropped.

It would be great to have the option to choose the display between "stretched/fit" to "cropped/center", "cropped/Left", "Cropped/Right", but setting it back to the display format it was would be fine in my book.

I know they're not urgent fixes but will help customize the look and feel if a person or business had multiple UnRaid servers, it's easier to tell them apart.
