The height to width pixel ratio of the photo is 4:3, the minimum upload ratio of the photo is 512 pixels high, and the JPG file with 384 pixels wide is: the set height to width ratio of the photo is 4:3, and the minimum size should not be less than 512 × 384 pixels. For example, if the height and width are set to 600 × 450 pixels, the ratio of height and width is 4:3.
According to the instructions, the minimum size is 512 * 384 pixels. If the proportion of the larger picture is 4:3, 1024 * 768 can also be used according to this requirement.
You can first create a 1024 * 768 image, and then paste your photos into it and adjust it to the appropriate size, usually in JPEG format. If you use PhotoShop software, you can directly use "Save as Web Format" to optimize it, so that the saved file takes up less space.
