What constitutes a high resolution image?

Image Resolution: The Spacing of Pixels

If images are made up of many tiny pixels, the resolution of an image is determined by their spacing. High resolution, such as 300 dpi, will show more detail in a given photograph. Colors and subtle features will also be more clear in a higher resolution image. The monitor of your computer is likely around 72 dpi, and it may be fine for the type of work you need to do. But, a photo that is only 72 dpi is not likely to suffice for many other purposes. For quality use of stock photos, you'll want a much higher dpi.
