Re-vamping my blog

   I've decided that my blog page needs a new look, however....I'm still trying to figure out how to do some of these things that I want to do!!! I found a header that I like (as seen above), but I can't figure out how to center it and how to get a picture in the frame. I'm sure it's simple, but man am I losing my patience trying to figure it out!!!! I also can't seem to get into my Template set-up....VERY frustrating!!!! If anybody can help me figure these things out, I'd HUGELY appreciate it!!!!!! Otherwise, you may just have to bear with me....it could be awhile before I get it right!!! :)
