I’m indocating that this discussion is had prior to engagement. However I am not implying that it should be a serious factor in seeing if a shidduch goes thru. At the end of the day the couple will need certain expenses taken care of for them.
Pictures 100% are reducing a bas yisroel to her physical attributes. Yes its important to be attracted to your spouse but deciding who you will go out with based on looks is a vile practice that’s antiethical to anything frum Judaism teaches. Ask anyone who is married if they thought their spouse was gorgeous on their first date. Majority will say no. Thats not to say they didnt think the other person wasn’t pretty. Rather, it shows that real attraction is something that develops as the other (more meaningful) aspects of a relationship develop.
