Profile pics with big fish...Yes or no ?,why?,
No. For a couple of reasons. But not like "No, that's a dealbreaker, I'm upset now that they posted that picture!" so much as "no, that picture doesn't mean anything to me or convey any useful information."
1. In many cases they're old pictures done on some trip long ago and going fishing is a rarity they haven't done for years or simply did that one time for someone else. Even if not, I have no idea it's not.
2. Many times people wear hats and sunglasses while fishing so you can't see what they look like.
3. I have no idea why they posted that picture, its importance to them, overall context or motivation. Is it their only picture? Do they like fishing? Do they just like boats and getting outdoors they just happened to go fishing that time? Do they find it ironic that so many other people on the site put up fishing pics so they did it too but don't really care one way or another about the activity?
Are they just insecure and feel they need to post a bunch of pictures to their profile believing it will mean greater "success," so it's ultimately just a filler picture or trying to be competitive with other profiles that have fish pics?
Put those together you get a false idea about the person, and mostly load it up with your own bias. What they look like, what they "really" enjoy, what motivates them, and something to judge (whether you "like" it or not, have in common, etc.), all of which actually retards any dating process.
Discussing it with them is pointless, as they can say anything they want, paint any picture, or what they think you want to hear, and there is no way for you to prove it one way or another.
It even retards the dating process as you build up a biased idea of who you think the other person is without actual experience of them.
You think you are going to be attracted to them enough to date them maybe stick around because they talked online about how much they like fishing and you have that in common, and they painted a magical romantic picture of themselves?
Or more turned off and want to run away because it turns out they're insecure control freaks as they spent the prior 2 weeks in real life micromanaging logistics to go on the trip, blowing off responsibilities, and taking out their frustrations on others until they can get out on the lake and go fishing, and then whine if their fish isn't big enough, or constantly gloat for months after that about their fish? None of which you would have heard about talking to them online and if you asked about they would have gotten bored talking to or being interrogated by you and ghosted?
Online talking, online pictures, don't mean anything.
It's not real until you meet and share experiences. Photos of the past, past experiences, are best used to create depth in whom you already know, not to decide if you want to know someone.
Otherwise it's just masturbating. Mental, emotional.
That's basically what "social sites" are. Sites where people post all sorts of pics of activities and past things. For people who want to play with themselves and pretend they are part of a social network and group, allowing them to escape from reality.
So big fish pic? Means nothing, unless you're not really looking to date and really just want to sit online and jerk yourself mentally and/or emotionally off.
If you really want to date and form a real, healthy, relationship, fish pics mean nothing.
If you're looking to hide from real relationships, preferring to use people for shallow short term gratification, fish pics mean whatever you want them to.
