What is the ruling on attending mixed-gender weddings that include music, and is it permissible to take a group photo of male and female students for memory?

It is not permissible to go to places of mixing or mixed weddings due to the resulting intermingling and looking at non-mahram individuals, and remaining silent about reprehensible acts. It is also not permissible for genders to mix for group photography for fear of women's images remaining with non-mahram individuals. Scholars have differed on the permissibility of photographic imaging without necessity or need, and the most cautious approach is to refrain entirely from commemorative photography.
