So I made that change. Here is the new script:

Code:
nick@server ~$ cat copy2.sh
#!/bin/bash
set -x

# The source directory where the photo folder on the phone is mirrored to
SRC=/hd1/home/nick/test1

# The destination directory where we want to copy only new photos we have copied before
DST=/hd1/home/nick/test2

# The MD5 list file that tracks which files we have copied before
MD5=/hd1/home/nick/test1.md5

# Check files against the MD5 list and then copy if not previously copied
# Then add the md5 for that file to the MD5 list
for f in $SRC/*
do
  FMD5=$(md5sum $f)
  grep -q $FMD5 $MD5
  if [[ $? -ne 0 ]]; then
    cp $SRC/$f $DST
    md5sum $f >> $MD5
  fi
done

Here is the new output.

Code:
nick@server ~$ ./copy2.sh
+ SRC=/hd1/home/nick/test1
+ DST=/hd1/home/nick/test2
+ MD5=/hd1/home/nick/test1.md5
+ for f in '$SRC/*'
++ md5sum /hd1/home/nick/test1/testfile1.jpg
+ FMD5='56eb2d747f5e0e08d8e743c968fc53aa  /hd1/home/nick/test1/testfile1.jpg'
+ grep -q 56eb2d747f5e0e08d8e743c968fc53aa /hd1/home/nick/test1/testfile1.jpg /hd1/home/nick/test1.md5
+ [[ 1 -ne 0 ]]
+ cp /hd1/home/nick/test1//hd1/home/nick/test1/testfile1.jpg /hd1/home/nick/test2
cp: cannot stat `/hd1/home/nick/test1//hd1/home/nick/test1/testfile1.jpg': No such file or directory
+ md5sum /hd1/home/nick/test1/testfile1.jpg


nick@server ~$ ls t*
test1.md5

test1:
testfile1.jpg

test2:
nick@server ~$ ~

ecaccess-file-move

ECACCESS-FILE-MOVE(1p)					User Contributed Perl Documentation				    ECACCESS-FILE-MOVE(1p)

NAME

       ecaccess-file-move - Move or Rename ECaccess Files

SYNOPSIS

       ecaccess-file-move -version|-help|-manual

       ecaccess-file-move [-debug] source-ecaccess-file target-ecaccess-file

DESCRIPTION

       Allow moving an ECaccess File. When the move occurs within the same ECaccess File System then it is a rename. When the move occurs across
       two different ECaccess File Systems then first a copy is done and then a delete of the original file is done (e.g. similar to ecaccess-
       file-copy ... -erase).

       The source-ecaccess-file and target-ecaccess-file are in the form [domain:][/user-id/]path. Please read the "Shell commands -> File
       Management" section of the "ecaccess" guide for more information on the ECaccess File System.

ARGUMENTS

       source-ecaccess-file
	       The source ECaccess File name.

       target-ecaccess-file
	       The target ECaccess File name.

OPTIONS

       -version
	       Display version number and exits.

       -help   Print a brief help message and exits.

       -manual Prints the manual page and exits.

       -debug  Display the SOAP messages exchanged.

EXAMPLES

       ecaccess-file-move ec:test1.txt ec:test2.txt

       Rename the test1.txt file in the ECFS directory of the authenticated user in test2.txt.

       ecaccess-file-move ec:test1.txt home:test2.txt

       Copy the test1.txt file from the ECFS directory of the authenticated user to the test2.txt file in the $HOME directory of the authenticated
       user, then delete the test1.txt file from ECFS.
