Can anyone explain how SmarterMail 16 loads the background images on the login page? It's silly thing and not a huge priority, but I can't figure out how to change them. Running 16.1.x and the help information is pretty weak. What type of folder path is needed for a custom image folder?  How is the photo selected?

 

I see the "MRS\Interface\img\backgrounds" folder with the images, but even deleting these (and refreshing browser caches) doesn't change the image. Nor does replacing images in this folder.

 

It's a cool customization feature...but the help file on how to implement it leaves much to be desired. Thanks,
