Googling the error indicates that it is coming from libjpeg:

JMESSAGE(JERR_CONVERSION_NOTIMPL, "Unsupported color conversion request")

You probably want the windowscodecs trace output to see where it is failing.

Looking at the parameter names they indicate that the resolutions are
in dots per inch (DPI), so that may complicate things a bit. As
always, this will need test coverage.

URL_ParseUrl is being passed a URL like "System.Xml" -- the function
is not handling this as a valid URL.

Here, tests will be needed to see how Windows behaves and the wine
implementation should then be improved to cover that/those cases.

Looking at the fixme's -- fixme:ole:OLEPictureImpl_QueryInterface ()
-- those interfaces are being requested for and not found in the
OLEPicture implementation.

NOTE: A test case will need to be added for each of these to check if
Windows actually implements those interfaces for the OLEPicture
object.

Something along the lines of:

IUnknown *picture = ...; /* OLEPicture object from existing tests. */
    IManaged * managed = NULL;
    HRESULT hr;
    int refcount;

hr = picture->QueryInterface(&IID_IManaged, (void **)&managed);
    ok(hr == S_OK, "OLEPicture should support IManaged: expected S_OK,
got 0x%08x\n", hr);

IUnknown_AddRef(picture);
    refcount = IUnknown_Release(picture);
    ok(refcount == 2, "Expected there to be 2 references to
OLEPicture, got %d\n", refcount);

text_picture_managed(managed); /* test IManaged methods */

IUnknown_Release(managed);

Manifest parsing should support xmlns:name="..." qualifiers for
elements as well as xmlns="..." qualifiers. This will need tests.
