Generally, would it be viable to rely on external picture hosting, like imgur or so?
In the past, looking for people on CS I found something like 3 – 5 pictures ideal. Not even necessarily of the couch, can’t remember having ever cared for a picture beforehand, of course I can’t speak for everybody.
Once I was hosted by a bloke in Vienna who would ask me some general things that would have been right at the beginning of my profile anyway. He excused himself for not having read it, stating that at some point he just stopped and now only decided whether to approve a request on the pictures alone. That strategy isn’t for me, at least not that rigourously; I did respect it a lot though.
