I've tried twice now.  I get a failure message from Mailer-Daemon@gnu.org for
the address bug-gnu-emacs@gnu.org.  Here is the returned message (below), minus
the encoded images.  Only two of the 3 encoded images seem to be present in the
returned mail, FWIW.

I had no trouble sending the same mail to Sean yesterday, with the same 3 images
plus 3 more.

This message was returned to me.  I'm trying again, but without the images that
displayed OK, in hopes that the problem was just the total size of the
attachments.

emacs -Q
 
I downloaded the GnuWin32 setup executables for image support and then
ran them, which put the image DLLs in a folder c:/Program
Files/GnuWin32/bin/.  I put that folder in my PATH.

These are the DLLs that I have in that folder:
 
glut32.dll
jpeg62.dll
libimage.dll
libpng3.dll
libpng12.dll
libpng13.dll
librle3.dll
libtiff3.dll
libungif4.dll
zlib1.dll
 
AFAICT, that should be all I should need.  What am I missing?
 
(In the same folder are lots of *.exe and other files.  There are also several
sibling folders.  I put only the bin folder in PATH (it is the one with the
DLLs.)
 
I have several image files and tested them in Emacs.  I cannot display
any PNG files.  I can display a tiny minority of the JPG and GIF files,
and I can display one of the two TIFF files I have.  When the image is
not displayed, what is displayed is instead a 1 cm x 1 cm hollow black
square on a white background.
 
I've attached two GIF images, two JPG images, and two TIFF images.  The
GIF I can see is beehive*.gif; the GIF I cannot see is drew-emacs-1.gif.
The JPG I can see is drew*palette*.jpg; the JPG I cannot see is
2006*.jpg.  The TIFF I can see is ftp*.tif; the TIFF I cannot see is
http*.tif.
