I hope this message finds you well, present circumstances excluded. My name is XXXXX XXXXX I am an attorney with over 10 years experience handling many types of claims in the litigation arena. It is an honor to be able to assist you with this matter.
The short answer to your question is that you do have rights to the public display of non consensual photos being displayed against your wishes. The mechanism to enforce those rights to prevent the display is to first have a temporary restraining order issued against the church for the display to prevent it from occurring. When you file for the restraining order (which you do not need an attorney to do for you) you can also request a hearing to have the restraining order converted into a permanent injunction.
The restraining order is rather simply to get and you simply need to go the courthouse in your county of residence and explain the situation to the court clerk and request assistance in filing for the restraining order.
To convert the restraining order into an injunction, you need to be able to prove that showing the photos will cause you irreparable harm to your reputation and that injunctive relief is the only mechanism available to you to prevent the release.
There will be a hearing on the injunction, in which case you can argue your position and request that the judge seal the record so that it does not become a part of the public domain.
In short, you need to file for a restraining order as soon as possible and request a hearing for a permanent injunction.
Let me know if you have any other questions or comments.
Best wishes going forward!
