Mumumw The sims and pets turning black with custom tattoos or paint were known bugs but should both have been fixed with the day 0 patch that released on Thursday:
Sims turn completely Black after Customization | EA Forums - 11972065
[CD] [HR] Pets/Horses are black | EA Forums - 12143277
If you're seeing sims or pets newly affected after that patch (1.116.223), please use this thread:

For the photos turning black, please use this thread:

Since this is a multi-report with existing bug threads, I'll lock it here.
