where do the minutes go....

Here i am sitting at the computer because I want a cute background like Lindsey Hill and Amber! I figured most of it out, in a matter of minutes, (YAY ME!) BUT I have the pic. in the "header" section that I can't get off. So instead of sitting here getting more and more frustrated I am hoping one of my good, smart friends can let me know how to do it. Also, how do I get the cute pics. of my friends on their links? (Kathy and Bri)? ok, now I am going to try to do something more productive while the girls are sleeping, maybe go squeeze that cute boy of mine who wants to play trains!
