| Subject: | imagepath and topimagepath accept only filenames |
The imagepath and topimagepath parameters to a Tk::Wizard object are
documented to accept a path to an image file, or:
"A reference to a Base64-encoded image to pass in the -data field of the
Tk::Photo object."
Attempting to use the latter yields:
"Can't find file at -imagepath: SCALAR(0x343e138)"
The following patch adds a simple check to avoid the "-e" check
producing that error message.
