There seems to be a little bit of confusion about this.
Generally we allow images up to 800 pixels wide but in picture threads you can post images up to 1024 pixels wide.
These are threads in the
Picture Gallery forum or
Digital Photography forum and threads of the "Post your desktop" or "Post a photo of ______" variety.
Images in all other forums and non-picture threads should be kept to a maximum of 800 pixels wide. You can use TIMG tags for larger images and the forum software will automatically reduce the image size. Users can click the image to display the full-sized version.
^^^ then your forum software is not allowing it or a setting is toggled wrong by mistake.
See below, I used to be able to post here and specify picture size simply by the "s800" or "s1024" or sXXX, the XXX being the pix width desired up to 1024 wide
I post 95% in the Digital Photography forum, it's one of my hobbies besides Home Theater and other "stuff".

It won't allow any wider than 800pix wide, hence my original post.
The post area is boxed in by a frame, and you have that width constrained......so that's why?
IS that for a clean white sheet look or future advertising strategy or?
My other forums, like Canon POTN,
http://photography-on-the.net/forum/showthread.php?t=1392239, or AVS forum for Home Theatre
http://www.avsforum.com/forum/19-dedicated-theater-design-construction/989861-envelope-home-theatre-2014-mike-r-mtbdudex-diy-11-3-audio-2-35-scope-130in-screen.html they do not limit the post area via framing.
For reference, Canon POTN I believe has a limit of 1600 pix wide (I was wrong, 1280 pix wide)

Image Size Limits:
Image must fit in a 1280 pixels by 1280 pixels box.
