Garry's Mod Mapping Textures

Hey, I’ve recently installed some cool textures for use in my maps. I can use the textures fine, but… when people download the map, will it come with the textures used in the map, or will they have to download these custom textures separately, because I have not always had CS:S and sometimes I couldn’t see there textures so I am a bit worried.
So… my question is, is there a way to package textures within a map, or get them to the down-loader?
