The the FAQ it says:

"There are 2 ways to do this. If you are using an unmodified stock template and have a GIF logo you can name your logo 'logo.gif' and FTP it to the YOUR_TEMPLATE/images/ directory."

Where is the YOUR_TEMPLATE/images directory? I don't need to make a custom template, just want to replace the small zen cart image. All I need to do is FTP the new logo.gif to the correct directory. Which one is it?

Thanks
