LWJGL - Issue Binding Texture To An OpenGL Quad

Newbie & Debugging Questions

Hello,

I’ve recently started toying with OpenGL, LWJGL and Slick2D. I’ve been having an issue binding a png (loaded into an instance of the Texture class) to an OpenGL quad. Currently it is just displaying a purple box the size of the texture. How could I correctly bind the texture to the quad?
