The size of the image setting must be a preset size, such as a width of 608px (PX means pixel), a height of 328px, and a resolution of 72PPI. It must be made in PS in advance. Each picture should be of the above setting size, otherwise the picture will be stretched and deformed. Pay special attention to the resolution setting. Because it needs to be displayed, the resolution of the picture can be set to 72PPI. Once the three pictures are set, place them on the desktop and import the three pictures in sequence according to Weitao's requirements. What I don’t understand is whether it’s one portrait display or three portrait displays. If it’s three portrait displays, it’s most likely that the width and height settings are reversed
