What is the difference between image size and resolution?
图片大小和分辨率有什么区别？
Image size refers to the dimensions of an image, usually measured by its width and height in pixels. Image resolution refers to the amount of detail an image holds, often measured in pixels per inch (PPI). A higher resolution means more detail and a sharper image, no matter its size.
图片大小指图片的尺寸，通常以像素为单位，比如图片的宽度和高度。图片分辨率指图片的细节量，通常以每英寸像素（PPI）为单位。无论图片的大小如何，分辨率越高，细节越多，图片越清晰。
