When development of How old i look started. there was an undeniable need for photos from people with their age.
As someone who tried many different resources like Flickr, twitter, Unsplash, instagram and some others. i can tell you that Pixabay was the best and instagram was a distant second.
I don’t mean that everybody accepted the request for publishing their photos in app, but many did.
and many were supportive and enthusiastic about the idea, to extent that asked me to tell them when app would be ready.
Pixabay community has been so supportive that inside of app’s database is a photo of Hans Braxmeier cofounder of Pixabay.
