Hi Tammy, My "day job" is in marketing and graphic design--I'm starting my own online store but still have a number of clients I work with. Most important...What do you want it to do for you? List those things and it will be easier to give you some advice :-) I'd be happy to pass on tips but not sure where to start for you!
which "theme" are you using at your site. The ones I looked at on their website seem to have all these functionality built into them?? Place to insert pretty banners, widgets for links and what not
I'm not sure exactly how wordpress sets up files but there should be a way to place an image into the header title area. There is some info in the forums (search "insert graphic banner)
Not sure is your site host is but they may be able to assist as well. I'd be happy to take a look for you as well (with no charge..if I can help you, great)
I sent you a private message..would be happy to take a look to see if I could trouble shoot this for you. LMK
