Image Verification on insert record

["Gary Woodward"]

Hi
I have a form that submits details to an access database using insert record 
behavior. However,  I seem to be getting a considerable amount of spam via 
this form.
Is there any way of using Image Verification (Captcha) as well as the insert 
record behavior on the same page?
I've used Image Verification on simple email forms before no problem, but 
this is proving to be more difficult.
Any help would be greatly appreciated.
Thanks
Gary
