In the following, the index file is placed in the requests directory, and the image file in the temp directory. The index files can have different extensions to indicate grouping or priority.
The pid file is used to prevent subsequent invocations of the cron job from running.
You can periodically examine the contents of the temp and request directories for entries that older than some specified time.


Code:
#!/bin/ksh
cd /u/email
BATCH=$1
proc=$$
if [ -r /u/email/$BATCH.pid ]
then
    echo "Previous batch  still running" $(cat $BATCH.pid)
    exit
fi
echo $proc >/u/email/$BATCH.pid
list=$(ls requests|grep $BATCH)
if [ "$list" != "" ]
    then
    for request in $list
    do
    #do processing here          
    #if successful 
        mv requests/$request done
        mv temp/$request* done
    #else
       #echo "This one failed"
       #fi
    done
fi
rm /u/email/$BATCH.pid
echo finished at $(date)
