OpenGL Different bit depths in a game

Most games give an option of bit depth whether you want 16 or 32. I was just wondering if you change it to 16, do they images you load in have to be 16 bit as well. I'm currently reading everything in and converting it to 24bit data for use in rendering, but if I change it to 16, do I have to load 16bit data in? By the way I'm using OpenGL.

The driver does the job of converting the texture format, so no need to worry about it. You can, however, use two different sets of textures anyway - one 16 bit and one 24 bit version. The 16 bit versions will use less memory an cause less bus traffic so performance will increase slightly.
The 16 bit option in games almost always refers to the framebuffer bitdepth, though, not the textures.
