you will need to find a picture on your pc you want to be that players face, then download fmXML, and an image converter that change Jpeg into PNG.
Go into my documents, then sports interactive, the football manager 2009 and go into graphics, if you don't have a graphics make one yourself.
in the graphics folder make a folder called players, go in that and make another folder called English Premiership, then inside that one called (what ever your team is)
In that folder you need to put your picture. Before you picture goes there make sure you have converted it to PNG format.
Now open FmXML, and were it says browse select the directory of were you players picture is. then click on go, a small box will come up, in here type the players unique id in and press okay
Close the program.
On your FM game go to preferences and click on display and sound. Untick use skin cache and tick always reload skin on confirm.
Then press confirm and the player will have the picture you wanted.
