Hey Guys,
Images Are All Back!
The reason they disappear is because the Forza servers can't handle all the downloads and they shut down the image servers because they are low priority. The Bugatti Chiron was released in a car pack when all the photos disappeared. The servers cant handle all the people downloading the car pack and shut down lesser priority servers. This also happened when FM7 was released.
I will update this if anything happens,
Hope this helps,
