I downloaded (wget) recursively the whole qresearch back in march.

That time there was over 25k .jpg/jpeg images

/qresearch/file_store$ ls -1 *.jp*g | wc -l
25611


Downloaded the python pixelknot detector (not perfect I guess). Modified the printing a bit and ran it.

Modified source here: cat pixelknot.test.sh
#!/usr/bin/python

import sys,getopt

with open(sys.argv[1],"rb") as f:
        block = f.read(6)
        str = ""
        for ch in block:
                str += hex(ord(ch))+" "
        #print ".",
        if str == '0xff 0xd8 0xff 0xdb 0x0 0x84 ':
            print "\npixel knot header detected!!!", sys.argv[1]
        #else:
            #print "knot a match"


These are the results I got:

/qresearch/file_store$ ls -1t *.jp*g | xargs -L 1 ./pixelknot.test.sh
