Unfortunately, this isn't being received well in some circles.
Among others, it's likely the "circles" that the in-laws belong to, knowing how they cherish their son's or daughter's wedding photos.
ETA: Just had the time to come back and click the link...to actually look at the photos and read the comments. Geez, saying they're blowing "smoke" in the air and at each other's faces. At least call it what it is...vapor, NOT smoke.
Personally, IMO there are
much worse things wedding party members could do, and have done, in wedding photos...than exhaling vapor into the air. Also, I didn't notice any that appeared to be happening during
the actual ceremony itself.
