I have recently shot a wedding. I have an agreement with the couple to let me use the photos for my promotional purposes. Should I wish to sell the image/s for books etc then a new agreement is required.

The wedding venue has asked for some photos to put on their brochures/website with me getting photographic credit and referrals. Since this is promotional but done by a third party do I need a further release (model release or the likes).

What are your thoughts any agreement I should have with the venue and their usage.

Thanks,
