What is the importance of ensuring that images are 300 pixels per inch high resolution?

Ensuring that images are 300 pixels per inch high resolution is important because it results in clearer and sharper images with more detail. This is crucial for printing purposes, as higher resolution images produce better quality prints with crisp details and vibrant colors. It also ensures that the image will look professional and visually appealing across different mediums, such as in print or on digital screens.
