--clearsign just generates a signature that includes a
'clear' (readable) copy of the document (not a OpenPGP message with a
data block that may be compressed or otherwise made un-readable without
a OpenPGP implementation processing the message).
This is *only* for stuff that can be read anyway like plain text. This
is not designed for binary content. For binary content just use the
normal sign option or use a detached signature.
--clearsign is just a extention for *text* only. It will be as readable
as the source data. PNGs can't be read directly by a user without a
picture viewer so the clearsign result cann't be.
Hope this was of some help :). Have a good day!
