[ferret_users] Insert / Paste a Logo on a Plot

["'Dr Kamoru Abiodun Lawal' via _OAR PMEL Ferret Users" <ferret_users@xxxxxxxx>]

Dear Ferreters,

Please, how do I insert or paste a logo on a plot? 

The logo is in gif format. For example:

...................................................

let my_logo = logo.gif
!let symbol = my_logo
 
!LABEL/over/NOUSER 5, 4, 1, 0, 0.60 "symbol"    !my_logo
!plot/over/title="m^my_logo" my_logo
 
set mysymbol = "my_logo"; annotate/over/user/x=0/y=50/siz=0.2/halign=0/valign=0 "<&mysymbol>"
 **ERROR: invalid subcommand: mysymbol = "my_logo"
set mysymbol = "my_logo"
Command file, command group, or REPEAT execution aborted
yes?

....................................................

Thank you!
