Show a status bar message when opening specific file extension

Question

I'm trying to setup a filetype option but I'm missing something on this:

filetype {*.gif},<image/*> echo "text to display"

because it's printed on the shell and not on the vifm status bar, already tried with :echo to no avail

edit:
I'm trying to make this work

%S Show command output in the status bar.

edit2: solved

filetype {*.gif},<image/*> echo "text to display" %S
