val[5] contains only one image but I saw that when printing out val[5]
is that the binary data is in a array. So this i what I did...

import array
[same code as before except for this... ]

print 'Content-Type: image/jpeg\r\n'
[...]
for val in resultats:
    p=p+1
    img=''
    t=''
    # t is an array object. the tostring() argument extracts the
binary data
    t=val[5].tostring()
    print t
and it works!
Thanks for your help Ben!
