This allows for 2 big features:
1. Artist can ship up to 4 prompts for image generation
2. Artist can regenerate images cause it is aware of seed
This allows for iteration on images maintaining visual style
Previous to this change image generation did not work on multisite
There was a background thread generating the images and it was
getting site settings from the default site in the cluster
This also removes referer header which is not needed
