just thinking about this a bit more....
You say you have
%lframe%Attach:{$$foxgroup}/{$$name}/{$$upfile_name}
on the target page, but you mean on the template page, yes?
You can use conditional markup with replacement variables
on the template page:
(:if {$$upfile_name} "":)
%lframe%Attach:{$$foxgroup}/{$$name}/placeholder.png
(:else:)
%lframe%Attach:{$$foxgroup}/{$$name}/{$$upfile_name}
(:if:)
Then you don't need a Fox filter for preprocessing at all.
