Any Computer Savvy Stitchers Out There?

I have been working out the changes I want to make to my blog, and one thing I really would love to do is enhance my banner with an image.  I have read an article on how to do this, but when it comes to these things I really need more information.  The article seemed to be written with someone who is a bit more knowledgeable than me in mind!  I need one of those "Dummies" books, I guess.  What I would love is a peacock tail all fanned out--and spread across the banner.  Of course I don't have this sort of image on hand and I am not sure about the whole copyright issue, so I guess I need to think about something different.  I think I will use my same colors, but at least change the layout--at least at this point.  Hopefully you will see a revamped blog soon!
