The signature plugin seems to be working just fine until you try to access the image after save. The image URLs given to me by the {Signature:<id>} do not work. They are formatted like this: http://www.<mydomain>.org/?page=gf_signature&signature=51db3b579fec37.51934275
I don't get a 404 not found or anything - just an image with no data.
Any ideas on how to troubleshoot? I already confirmed that my wp-content directory is owned by apache and has CHMOD 755. Not sure if the data is being saved in a flat file or database to troubleshoot further.
