For the WADO RetrieveFrames option, the media type used inside the code is :
        if (type == "image/dicom+jpeg" && transferSyntax == "1.2.840.10008.1.2.4.50")
        {
          return gdcm::TransferSyntax::JPEGBaselineProcess1;
        }

But, the type is :image/jpeg" is image/jpeg in Table 6.1.1.8-3b of "DICOM PS3.18 2016c - Web Services" document.
I tested in a version built by myself, for VS2015.
