Data from web form to Access

[Graeme at Raptup]

I have an Access database for which ideally we would have a front end form on
the net. The form is for clients to submit artwork data (e.g. prices and
volumes) as well as jpeg images.
With my limited knowledge of servers and programming I found someone who
will develop the form for me. Problem is how do I get that data into my
Access db? i.e. What format should I ask him to provide and then what is the
best way to import.

I am comfortable importing from spreadsheets so that is not completely
foreign.
Any advice always greatly appreciated.
