I prefer the option Fly_zo suggested but with a map related prefix in the final file name so that you can identify both the author or team and the map set the texture was created for.

Example: (for World War One Western Front Map)

...\MODS\MAPMODS\maps\_Tex\ WWI_WF\land\summer\WWI_Shellholes.tga


Grouping all the textures for a particular map in a single primary folder simplifies installation, especially for those who prefer to manually install everything.
