First of all, I feel like you should buy a high snapscore or an account with a high snapscore (over 60k-70k). Foids will NOT believe that a Chad is who he is unless you have a high snapscore.
Second of all, just find as many pics as you can and post them. If you want to send multiple pictures to her, and you can't find any, start to adjust lighting, contrast, etc and stuff and zoom in the picture, like zoom in the Chad's eye or something as a pic. Or just stop sending them all together and do like random shit.
I'm not a professional Chadfisher, but I've done shit like this before.
