To understand the issue of 'resolution', you must understand the difference between 'pixel' and 'byte'. If you don't, you'll ask vague questions and receive misleading answers.

Resolution is properly understood as pixel resolution. Pixel resolution is very simply the length by width of an image, measured in pixels, and typically divided by 1-million to express as megapixel.

Therefore, an image at 6000x4000 is 24 megapixels or 24MP (6000 * 4000 / 1000000 = 24).

'Bytes' are a measure of storage. Bytes do not equal pixels. Pixels and bytes are not interchange terms, just a dark chocolate and 4.72 ounces are not interchangeable terms.

'Pixel' has a slightly different meaning in different contexts, but a pixel is generally thought of as the smallest single component of a digital image. As the smallest component of a digital image, a pixel is described by 'data' within the image file. That descriptive data has a storage size expressed in bytes. Images with more pixels contain more bytes making the files larger in size as expressed in bytes (or kilobytes or megabytes - MB). The data needed to describe a pixel varies based on the type of file and some techniques used to compress the storage size of this data. Therefore, you cannot take the pixel resolution and say with certainty how big (or small) the size in bytes of the file.
