What is the width and height of a 2MB picture?

The picture is composed of pixels. If it is a bitmap, assuming it is 32 colors, 2M=2*2^20=2^21, 32 colors is 2^5, which is 256*256. The 2M specification marked on a digital camera refers to two million pixels, generally referring to the format of 1600X1200. The file size is not necessarily certain, it changes depending on the color and depth of the image.

The picture is composed of pixels. If it is a bitmap, assuming it is 32 colors, 2M=2*2^20=2^21. 32 colors is 2^5; the remaining 2^16=2^ 8*2^8; is 256*256.

On digital cameras, the standard 2M specification refers to two million pixels, generally referring to the format of 1600X1200. The file size is not necessarily certain, it changes depending on the color and depth of the image. The 2M in the computer is the text size, and the unit is B bytes.

Extended information:

2MB is 2000KB, K means one thousand, one K=10242MB is 2000KB, 2G is 2000MB, in thousands. The actual unit is 1024. The size of the photo is determined by the pixels of the camera. For example, use 8 million pixels.

Photo 2M refers to a photo with 2 megapixels, generally a 4:3 ratio, and a size of 1600*1200. The specific file size depends on the precision of the camera settings, and generally does not exceed 1000KB.

This size is not certain. It depends on the accuracy of the picture. If it was taken by a digital camera, it depends on the pixels of the digital camera. 1024*2=2048KB, the size is calculated based on the resolution, 800*600=480000, 800 and 600 are pixels, 480000 is the resolution of 480,000, which is the size of the photo.
