hopsing45, Please read the manual that came with FPSC alot of the questions you keep asking are answered in there
Also download and read the hints and tips guide from this thread:
http://forum.thegamecreators.com/?m=forum_view&t=93081&b=21
Now onto your question go to File then Build game. When the window opens click the Level settings tab from the top. Then look at the scripts specified at the top you will see the third one down is the global script, click the edit button on the right hand side of this all the properties including the HUD image and position can be changed from here.
Good luck and don't forget to read that stuff you will feel clever afterwards
Thanks
Adam
