While my PC doesn't have problems loading threads with big pics, I'd also welcome a solution to that. Don't get me wrong, big pics are great, but in some cases they're just far too big to be of any actual use. Take the F-35 thread, for instance. Of the recent bomb drop pic, I can only see the F-35's forward fuselage. Anything aft of the pilot needs to be scrolled sideways.
Over on ARC, the software automatically resizes pics that exceed a certain size (to be determined by the admin, AFAIK) to that size. Clicking them will toggle the full size view. Clicking them again will revert them to their reduced size. The maximum width is 1024 pixels, I think. Anything larger will be reduced to a width of 1024 pixels. Personally, I think that's a good solution. I don't know whether our forum software has a similar feature, though.
