                    Thanks for any help and suggestions.  
1. I installed a logo to FTP server in images file, titled logo2
2. I checked "YES" on setting page, and pasted the logo2 url and saved
3. When I go to the site, no logo, and a drop down appears to enter my password....?
Being new, I do not understand where exactly to put my new logo image, and do not know where to get the url that needs to be posted in the settings url for logo. 
Thanks for your help! Trying to learn.
