I think it was Smeg not the press who wanted to portray Thomas as a slob. She sent Jeff Rayner her long-time pap to Rosarito to suggest a few photos before the wedding to "improve his profile". Rayner would not have done this without her say-so and she will have paid for the trip.
She told Jeff to tell Thomas she'd sent him, and offered him money for some photos. ( It's possible Smeg sent some money via Rayner on his visit and this was later twisted to being payment to her dad for the photos? ) Believing he was going to the wedding Thomas went along with it.
Offering money was crucial to her plan to portray Thomas as having sold her out, as it wouldn't have had the same impact if he'd done it for free. The photos were used to discredit him so she could wail that her greedy daddy had sold her out. She leaked Jeff's photos to the press - plus fact that Thomas been paid - and Thomas's name was mud.
It was an excellent plan, worked a dream. As she had always intended Charles walked her up the aisle, her family was trashed in the media and shortly afterwards her dad had a heart attack. Inmate Doritto will have known all about it, the creep.
This is my theory but there's no proof, though if there's a trial we might learn more.
