How to display high res photos in the game?


What is the best way to display high resolution photos in der Game world, without compression loss? As soon as I display the photos in the world, they lose details.
And is it possible to display textures directly without having to rely on light sources (Emissive materials included)?

Because if the images are displayed in the game, the colors and the brightness are completely distorted.


Are you using decals to display the images? Have you tried to set the material to DB-buffer(not sure what it is called…)? When you say quality do you mean resolution or something else?
