Photo resolution refers to the number of pixels that make up a digital image. It is typically expressed in terms of width x height, such as 1920 x 1080 pixels. The resolution of a photo determines its quality and how large it can be printed or displayed without losing detail.
There are several reasons why you might need to check the resolution of a photo. For example, you may need to ensure that it is high enough quality for printing or use on a website. You may also need to check the resolution to determine if it is suitable for a specific purpose, such as social media or email.
