You should be able to disable the logo by adding the following to your CSS:
.Banner img{display:none}
when you get a new logo, remove that change, and your logo will appear.
I did what you suggested and it got rid of the place holder, thank you. I have now added a new banner and removed the entry. yet I still have a place holder and no new banner? I even uploaded the .jpg file to the admin directory and no fix. I have a feeling it is a flaw in the template I am using. would you be able to give anymore more insight? here is my site again for review.
