Can't seem to find how to do? No issue with picture uploads on the Forum, just with PM'S. I see the URL upload but I want to upload from my computer files.
Don't know that's its possible on any of the forums. I often just share email addresses and work it out that way.
Good luck
If you are trying to send someone a picture in a private message I believe you need to upload the picture to your gallery then copy and paste the BBCODE in the private message.
