Sorry, I thought I'd done that in the lines -

# add the image to the current session
$::session addImage $l_image_file

addImage is surely the method, and l_image_file is the variable???


You are not setting the ::session variable here, you are referencing
it ($::session)
Add this point the error indicates that $::session is "" so this is
substituted to:

"" addImage $l_image_file

giving the 'invalid command name ""' error.

Maybe you meant ::Session::addImage instead? I did notice that this is
defined as:

body Session::addImage ...

Is body some procedure you wrote yourself?
