I dont know if there is any simple way of achieving this. However, I had similar issues with sharing high quality images and whatsapp was not the right app for it. I setup slack for my parents on their phones and they share images and stuff on it. The free tier for slack works for me, and integrated tons of apps like dropbox, kayak and etc to it. But then this is more suited for close group, like in my case.
