Emailing myself out of my cloud
accounts is a lot of extra work for just a forum picture. I don't have this issue anywhere else I frequent on the internet anymore, except older board style forums. It happens with both my Android and my husband's iPhone images. It is a LOT easier to add pictures from outside albums.
I know vBulletin has know about the issue for years and chosen not to address it. It is baked into the hosting platform. I thought there was a patch that came about in the last year or two. Tapatalk still does it too.
