I think your description makes plenty of sense. While I do not run this particular website, I have had a bit of experience in the operations of sites. The short answer is "probably not". I'm sure there are some message board systems out there that can do this, and this one may be one of those. But, typically a picture that is sized to 640 pixels wide (or less) should fit *most* threads. That of course depends on your monitor and video settings. If you only run in 800x600 video mode, none of this applies :)
