Up to this point, we have only talked about half of UV Textures; the UV map and layout. The layout is the arrangement of all the UV maps. Each UV map 'maps' image pixels to a mesh face. There is one UV map for each seam or sub-mesh. The entire layout is colored by an image. Blender provides several features that help you when working with the image part of the UV Texture. Blender also includes a built-in texture painting program. This tutorial discusses how to use images effectively.
