I need to batch rename and relink files in indesign

Question

I have a whole bunch of files that I need to rename ( I need to add a prefix on to the front eg. a whole group of files called "plan.jpg" 01.jpg, 02.jpg, etc... need to now read ORD_plan.jpg, ORD_01.jpg, etc...) I can batch rename the files in adobe bridge, but I have to go in one by one and re-connect the links. Is there a script which can batch rename and relink all the files? 
Thanks!

This biterscripting script may possibly help. It takes two input arguments.
directory - directory under which the .jpg files are located
prefix - prefix which will be added to each file's name
# Script RenameJpg.txt
var str directory, prefix, list, filepath, name
cd $directory
find -n "*.jpg" > $list
while ($list <> "")
do
    lex "1" $list > $filepath ; stex -p "^/^l[" $filepath > $name
    set $name = $prefix+$name
    system copy ("\""+$filepath+"\"") ("\""+$name+"\"")
done
This is the way you would use it - copy and paste the script code into file C:/Scripts/RenameJpg.txt, then enter this command into biterscripting.
script "C:/Scripts/RenameJpg.txt" directory("C:/test") prefix("ORD_")
It will rename C:/test/plan.jpg to C:/test/ORD_plan.jpg, C:/test/01.jpg to C:/test/ORD_01.jpg, etc.
Important: I am using the 'system copy' command so that files are copied instead of renamed. Once you are happy with the test, you can change that command to 'system rename'.
Also, if the .jpg files are within subfolders of C:/test, change the 'find -n' to 'find -r -n'. -r means recursive = search in subfolders. Syntax for the find command at http://www.biterscripting.com/helppages/lf.html
