What is the resolution of an image?
The resolution of an image refers to its pixel density; that is, the number of dots per inch that make up the image. Higher resolution pictures print better than low-resolution pictures, but have larger file sizes and thus take longer to download. The sharpness of the image on a display depends on the resolution and the size of the monitor. The same pixel resolution will be sharper on a smaller monitor and will gradually lose sharpness on larger monitors because the same number of pixels are being spread out over a larger number of inches.

Image resolution has to do with the amount of information or detail contained within the image. It is measured using different terms depending on what industry is describing it. In the world of electronic images it is measured in ppi (pixels per inch) while in the world of graphics it is measured in dpi (dots per inch). In any case the greater the ppi/dpi the greater the resolution or detail within that image and the larger the amount of memory required to store it electronically.
