insert image path to database id

[eluser]Unknown[/eluser]
I haven't got to using the catergory_id database yet as i thought it would be easier to start with first posting the ads then later put them in categories.

what is this upload helper? not really sure how i would use it for my website

and i am aware that $ad_id isn't being reference from anywhere, that is my question, how do i reference it from the database once the ad for is posted?
