I am trying to upload pictures to DotPhoto via FTP. Everytime I try to upload, I receive a message saying "Access Denied." I have tried both gFTP and the terminal ftp but received the same message. I was able to upload pictures just fine using a Windows machine so the problem must be on my end. Here is the output from gFTP:
