SSH and script weirdness

We have created a script to capture an image from a webcam and deposit it into a folder so it is available to the web. The script was created by a colleague who SSHd into the server and placed the script on the root level in a folder called scripts. the script works flawlessly when he kicks it off as sudo from the SSH connection. It deposits a 50Kb file into the folder and all looks great. When I initiate the script locally via sudo I also get a file in the folder. Problem is it's 0Kb, and there's no there there... Looked at all the permissions, and they look all right... Any ideas? Thanks Phil
