PDI ENTRY GUIDE

Updated: September 2025

Firstly, edit your image the way you like it. This includes adding any stroke lines and borders. This should be done as part of the main editing, so that you don't resize it then make it bigger afterwards!

If editing in Photoshop, Affinity Photo, etc., flatten all layers.

Next, resize the image so that regardless of whether it is a landscape or portrait orientation, the size should be no more than 1600 pixels wide by 1200 pixels high.
