Is it still possible to produce items/ships/etc. with custom images attached, and if so, how would one go about implementing these customized productions? Thanks for any assistance regarding this matter. Cheers!
since an NFG isn't a entity in any way, it can't.
Player can assign custom images but only after the production.
Factions can assign customs to a product before the production starts.
For this a producing faction (not the DC-holding faction) has to request a custom image via the dc-exchange page.
After the image is accepted it can be choosen via the producing page (change image) in any factory/yard.
