Try (if you are sure the file have JPG extension and not jpg):
Code:
#!/bin/sh
filecount=1
filesize=0
mkdir $filecount

ls *.JPG | sort -n | while read FILE
do
	filesize=$(du $FILE | cut -c1-4)
		echo $filesize
		if [ $filesize -gt 2000 ];then #dumps file into existing $filecount folder - is a useful image rather than a marker image
		  echo $FILE
		  mv "$FILE" "$filecount"
		else #creates new directory when marker image is discovered
		  let filecount=filecount+1
		  mkdir $filecount
		fi
done
