Subject: [PATCH] Add a comment about a patch to be able to reda wrong images,
 wher UN length is coded on 2 bytes.    // WARNING :    //    // For some
 images, length of UN elements is coded on 2 bytes (instead of 4)    // There
 are *not* readable !    // You can make a quick and dirty patch, commenting
 out    //| vr == "UN"    // in the following line.    // (the 'straight'
 images will no longer be readable ...)

      if ( vr == "OB" || vr == "OW" || vr == "SQ" || vr == "UT"
                                                          || vr == "UN" || changeFromUN == true)
