I believe it's not a bug per se, but a bad interaction between the way people take pictures with their mobile devices and the software we use to see the pictures.
When you take the pictures with the mobile devices, the "home button" should be either on the bottom or to the right -- if you take pictures with the home button anywhere else, the device will shoot the picture and mark it (properly speaking, the picture will have metadata in the EXIF Orientation or Rotation tags saying the picture is 90CW, 180CW or 270CW) so that the end-user software can properly rotate the picture so it can be seen the way it was taken, instead of upside down or to the side.
Some browsers will show the picture correctly if you right-click the picture and tell it to open the picture in a new window/tab, some will not.
In any case (and please keep in mind I'm not an expert in web stuff), here's what you get when you right-click the pictures and choose "inspect element":
The picture is displayed "in-line" with the thread, you get code like < img src="

The picture is opened in new window you get code like < img style="-webkit-user-select: none" src="
http://www.vacuumland.org/TD/JPEG/VINTAGE/2013/cam2s++5-19-2013-21-21-35.jpg">
I'm not sure how to fix the situation, but I figured that people who deal with web software will probably recognize if something is wrong and how it can be fixed.
