You can download facepacks (like GillsMan's in the thread in this forum) and install them yourself:
- Unzip each folder to "C

Documents and Settings\<your name>\My Documents\Sports Interactive\Football Manager 2007\skins"
(all custom data should be stored here: if stored with the default game files it may be overwritten by patches)
- Run FM 2007 and either load a saved game or start a new game. Once loaded, open "Preferences" from the "Options" menu.
- Under "Display & Sound" untick "Use Skin Cache" and tick "Always Reload Skin On Confirm".
- Confirm your new preferences. The facepack should now be loaded.
