Are you using "Fill & Sign" to add signature? If not, click on "Fill & Sign" option on tool bar and select sign icon at top.
Take help from this KB doc Sign PDFs in Adobe Acrobat Reader. and Check if you can add image from there.
my version is 11.0.14. Mac 10.5.9
I am using Fill and Sign as I always have but just last month it started to open a window that asked for a Digital ID and I could not go any further. I have read some of the links above but I have not found how to delete this request for a Digital ID. I have spent some time in the Preferences trying to change signatures and signatures enhanced with no luck.
I just want to go back to the old way. My office PC that does have an updated Acrobat allows an image signature, but that new version does not seem to allow me to change the type font when I want to add text. Thanks for your advice on deleting the Digital ID. Joe
