It is supposed to have flipflops for the background...

I have been snooping on my sister's friends blogs and found this neato site to get different and fun blogger backgrounds.  So I followed all of thee instructions and downloaded it to my blog and no flipflop background.  POOOH!!  I like the colors and layout but now I have this annoying orange strip across the top and all these question marks and nonsense.  Now, how do I fix it or get it off?  I am so not savvy about this.  I still haven't figured out how to put random pictures that aren't from my camara on or to put my own playlist of songs.  I have a great, cute playlist with all Disney songs and still can't get on myself. WaaaaaWaaa!
