Skins dont work this way?

[Jelly]

I installed skins onto my server, i uploaded the bzip2 version of them to the fast download website and when i enter my server, it gives everyone a big ERROR sign. Also every time i change the map, it automatically redownloads the skins. i tried not using the fast download and it worked perfectly (no errors, only downloads once). anyone know how to fix the problem with the fast download? maps are taking forever to download -.-

you have probably configured the fastdownload the wrong way

Please give a more detail response of your problem.

Such as listing what mods/plugins you are using to use the skins on the server.
