I always upload my pics to Imgur. Then I get the links from there and post them on forums. I've always done it that way and it's always worked.
Also, I'm on my PC, not my phone. I HATE using my phone for internet (although I did take the pics with my phone and uploaded them to Imgur on my phone). I also HATE getting old...lol.
But I'll try attaching them to see if that works.
