Picture resolution refers to the number of pixels that make up the width and height of a digital image. It is typically expressed in pixels per inch (PPI) or pixels per centimeter (PPC). The higher the resolution, the more pixels are packed into a given area, resulting in a sharper, more detailed image.
Checking the picture resolution can be important for several reasons. First, it can help you determine if an image is suitable for a specific purpose. For example, an image with a low resolution may not be suitable for printing, while an image with a high resolution may be too large for a website. Second, checking the picture resolution can help you troubleshoot image quality issues. For example, if an image appears blurry or pixelated, it may be because the resolution is too low.
