This is a problem encountered with all members that use anim8or it will look for the area that you got them from initially ie:c/ textures/ so if you share a .an8 file with anybody else unless they attach any relevent textures ( which half The time they dont!) then the model will be textureless. especially so if those textures are on another Drive, flash card etc. So long as you keep your textures in one area they should be ok.
I have recommended users use the system that Daz, Poser, and Carrara adopt by using an Anim8or runtime system. for sharing ( carrara has the ability to save all textures internally in a any case )

I never did find out what the File section in the textures was, perhaps that was something Steve had in mind, to store textures internally, but, like IK has never been implemented.
