Photography Release Form Questions

I am looking for a form I can use that will give us the rights to publish and use images of weddings/receptions that are held at our wedding venue for general advertising (web and print). As we are not the photographer but the location these photos are taken at, I am not sure what I need to include legally in this form.

Do I need the photographer to sign the form to allow me to use their images? And if this is the case, should both the bride and the photographer sign the same form or can I use a separate form for each?

Would anyone have any examples/templates I could look at for the release forms?

Thanks,
