Notes:

• Pixels (px) – A unit of measurement for digital images. Your photos will need to be cropped to a set width and height in pixels, which is the overall image dimension.
• Bytes (KB, MB and GB) – Measures the file size (weight) of digital files. 1000 Bytes = 1 Kilobyte; 1000 Kilobytes (KB) = 1 Megabyte; 1000 Megabytes (MB) = 1 Gigabyte (GB)
• Image Resolution (dpi or ppi) – The amount of dots (or pixels) per square inch of an image when it is printed or displayed. A higher-resolution reflects a higher image quality, and is most important when printing an image.
