SIZE
When you are preparing pictures PDI Competitions
  • LANDSCAPE - Images are not wider than 3840 pixels or taller than 2400 pixels;
  • PORTRAIT - Setting the height to 2400 means the width will be less than 2400;
  • SQUARE - Images will be 2400 x 2400;
  • Do NOT fill any unused area - this is not required.


NAME
Save each of your resized images as a jpg file with minimum compression (100% quality) and use the sRGB colour profile.
