UK Spouse Visa Photos

Hi

Do the photos that you send as part of proving the relantionship is genuine need to have date and time to show when they were taken on them? Or are just plain photos of you and your parnter without any date stamp fine?

When hubby applied for his spouse visa we just sent pics in different places at different times of the year. I wrote on the back of the photos the month/year/ location and these were accepted.
