A signature includes a certificate - that's how the technology works.  If you 
don't have the certificate - you can't sign ANYTHING.  (not a PDF issue, but a 
Digital Signature issue).

I don't understand the question.

Are you talking about digital signatures?
Or just about a "sign", some "image"?
You'll have to clarify.

Try explaining what you want to do in pseudo code.
Maybe that will be easier for us to understand.
