Each image has three specifications: Original (original image): An original image refers to an original image sent. The dimensions and size of the original image remain unchanged. Large (large image): A large image is obtained after the original image is proportionally compressed. After the compression, the smaller one of the height and width is equal to 720 pixels. Thumb (thumbnail): A thumbnail is obtained after the original image is proportionally compressed. After the compression, the smaller one of the height and width is equal to 198 pixels. If the size of the original image is smaller than 198 pixels, the original size is retained for the three specifications and compression is not required. If the size of the original image is between 198 pixels and 720 pixels, no compression is required for the large image and original image. When an image is displayed on a phone, we recommend that you display the thumbnail first. Then, the user can tap the thumbnail to download the large image and tap the large image to download the original image. Developers may also choose to skip the large image, so the user directly downloads the original image by tapping the thumbnail. When images are displayed on a tablet or PC, because the resolution is high and the devices are usually connected to Wi-Fi or a wired network, we recommend that you directly display large images. Then, the user can tap the large image to download the original image.
