Hi Wahsayah,
No, you don't sound like a fool asking that question.

However, this forum is only for completed graphics modpacks, rather than general questions. It would be preferable to post the question in the main C&C forum, here:
http://forums.civfanatics.com/forumdisplay.php?f=46
About your question, I'm not sure whether you just want to know what graphic to replace, or also how to place it in the correct format (with no palette problems, etc.). If you wish to know what file to replace, and have a replacement in the correct format, in the "Art" folder of the Conquests folder (assuming you have Conquests, otherwise it's the art folder of the original CivIII or of PTW, whichever is your latest installation), you'll see a file called x_title.pcx. Just backup that file (for example, I renamed mine x_titleORIGINAL, and left it there), and place your replacement title screen pic, called x_title, in the folder. If you have Conquests, there is no point replacing the x_title pic in the original CivIII Art folder, or the one in the PTW Art folder, as the game will use the Conquests one first. Just replace the Conquests one and you'll be fine.
If you just needed to know how to put a picture in the correct format, then please ignore the above, and please re-ask the question in the main C&C forum. I would gladly explain it here for you, but unfortunately I have to get off the computer now, and I won't be back on for a couple of days.
Good luck with replacing the title screen!
