Draw Image behind everything rendered similar to skybox

[Slastraf]

Hello

Basically I want to draw have an image in the scene behind everything, but I need to have wireframe enabled. So I cant just place a face with a texture and put it behind. The skybox is also rendered in wireframe mode. So I need to have an Image Drawn before everything renders but this is impossible because I believe every pixel has a color value to it which renders over the drawn image. 

I also saw a thread (I think in c++) before about a similar problem from about 2014, and it said that there could be a feature for this implemented soon. So is there a feature for this ? Or a workaround ? In this photoshopped picture you can see that Leadwerks is visible but behind everything.

found a workaround, if you place a tree far away for it to become a billboard it has the same effect so you need to apply it

//EDIT it wasn't the billboard but the polycount of it :/
