That works fine if your /home/conni/eule.gif is on the server, but what I
was wanting was the process to insert when your on a remote system and your
/home/conni/eule.gif is on the remote system not the server. You can use
the \lo_import <filename> to import a local file to the server, which then
can be seen with \lo_list and exported with \lo_export and then \lo_unlink
if you wish.

How do you put the OID into bild from the large objects list? I'm not sure
what the use of \lo_<cmd> is?
