Sending your image in to the paper as their announcement would still quality as 'personal use' as far as copyright goes (well, with me it would still classify as personal use).

I personally wouldnt be worried if my name wasn't mentioned, I would feel differently though if it was a feature article on the bride and groom's day.

The issue is the 'implied artistic accreditation' given by having the paper's photog as the only listed name.

I hope the paper will rectify this in the future after your email.

I would make sure in future you have all of this in your Terms and Conditions for the bride and groom to sign, if you havent already
