So as to reduce the amount of server space used for images, we have imposed a limit of image size to fit within a square of side 1200 pixels. This is big enough to see plenty of detail, but should reduce the load on our storage space. So, please ensure that your images don't exceed that size, or you'll get a message advising that they has been rejected!
Of course, this does NOT apply to the competition upload system on the main club website, which still accept images up to 3840 wide by 2160 high (for 4k uploads) or 1920 x 1200 (for HD images)
