just a note

Sorry I keep changing the look of my blog.  I like BIG, and this is the only way I can make my pictures bigger and still be able to fit them into the alloted space.  However, my header is now too big.  I have resized the picture so many times and I can't seem to get it to look right (I want it to be long and skinny).  I'm not savvy enough to know how to change the HTML code or whatever instead of resizing the picture, or maybe I need to do both.  Maybe I'm making it too complicated.  Can anyone help me?
