David,

I've always seen Mapserver/AGG putting the PIXMAP symbol centered CC
onto the point geometry, and this seems to be confirmed by a quick look
at the code in mapagg.cpp.

I might add, though, that I always define a symbol for any PIXMAP in my
symbol file before using it in my mapfiles. If the path to the image is
given directly inside the mapfile or there's a binding to a field as in
your case, things might actually be different. Still, it would seem
quite odd to me...

Best regards,
