If you uploaded a photo called "portrait.jpg," the actual file would be located at the address: http://yourdomain.com/content/photos/portrait.jpg . To get your gallery to appear at just "http://yourdomain.com/galleryname," you'll need to upload into a different directory.
Using your FTP program, navigate up a couple directories from photos, into the "www.yourdomain.com/web/content" directory. This is done from within your FTP application (CyberDuck, Transmit, Fetch, or Filezilla). Once you upload your gallery folder (call it whatever you want), it will then be located at http://yourdomain.com/galleryname/
It's very helpful to name the folders simply--one word, no spaces, all lowercase.
