Just measure - drivers licenses are a standard size!.
Business cards are 2x3!.5" and are narrow so photos are probably 2!.5x3!.5Www@QuestionHome@Com

all wallets/purses are different
you might needa cut down the pictures to fit
if there too small stick them to a piece of paper
then put them into your wallet
