I was able to upload the website logo and backend logo, but not the INVOICE logo.
I get this error
[COLOR=“Blue”]Cannot create the file /home/derbysmack.com/skins/electro/mail/images/beanie-logo-1-white-small.png. Please check the directory permissions[/COLOR]
I have that folder set to 777 but still have issues. 
Need to verify all path elements from the root of your store to the destination. Is there a file there already that might be write protected?
