Thanks for your reply.
I thought I was a member, but nobody told me there was a secret handshake.
I tried the little postcard. That's what rejected my URLs.
I've been searching this site for photo upload rules, "640x480 jpg under 10 kB", or whatever.
Photobucket put up a paywall. I left. Searched "free photo hosting", but B-UK doesn't seem to accept https URLs, only http. Weird.
I did data analysis for a marketing firm. I've pulled the personal data of Facebook users. No thank you, I won't use any Facebook-owned app. Too bad, WhatsApp was good. Friend, I recommend that you switch to Signal. Better encryption and no tracking.
Cheers,
