this is an illustration created by me in cs5 and I have to now scan the image on my own work for each drawing that I now do on a property release? makes no sense?

Only if you want them to be accepted... 

If the image you submit was traced of a photo or other image or is a picture of artwork ("scans/photos of paintings") you need to add a property release which have included in it the original image from which you worked or a release for the artwork creator itself. I save a jpg file of the original and add it to my release (in MS Word) which I then print to JPG or PDF file and submit that.

If the work is original yours (not traced), I have mentioned this fact in the note to the reviewer "This is not a traced image, it is an original work of art. There is no source document which can be attached". I non the less attach I generic property release stating that the image is my own work.

Glad to be of help. Hope your images gets approved now.
