The 2018 Interclub Preselection PROCEDURES AND RULES document contained an error in the Image Specifications. The Maximum Horizontal Dimension should be 1400 pixels (not 1440 pixels). The downloadable PDF copy of Procedures and Rules has been corrected.
Repeat: Maximum image dimensions are 1400 horizontal × 1050 vertical pixels.
Apologies from Ed, and thanks to Ann for inadvertently being the clever guinea pig.
