Texture format list

hi there,

has anybody an idea where to find in the world wide web, or perhaps even in the deeps of this wiki, a list which explains the different texture formats?
i 'm talking about the r8g8b8 things. some of them are quite self-explaining, others, well, no.
all i found so far is this.

thanks,
philipp

there is a very good reference for direct3d on msdn. like here the D3DFormat Enum.
