No, but a quick search on bugzilla for OleLoadPictureFile turned up bug
10156. A comment on that bug suggests changing the summary to
"OleLoadPictureFile not implemented", which would exactly sum up my
situation. I posted a comment to that bug to that affect. Should that
bug be renamed, I could post my findings there...

I've been looking at writing some tests (I've been compiling using make
crosstest and running the exe on windows 2000), and I've found that there
must be some sort of mapping between error codes from GetLastError when
accessing the file and the HRESULT values returned from OleLoadPicutreFile
(and not of the standard HRESULT_FROM_WIN32 variety that I'm familiar
with). For instance, CTL_E_FILENOTFOUND is returned when the file does
not exist. I'm trying to invoke as many error cases in the test as I can
to flesh out this mapping, but I'm not sure I can find all of them in this
I think at some point in the next couple of days I'll decide I've got as
many as I can and send in a patch to the tests.
