How many pixels are in a 3mb picture?

The number of pixels in a 3MB picture can vary depending on the image's color depth and compression. For example, if the image is uncompressed and uses 24 bits per pixel (8 bits for each of the RGB channels), a 3MB image would contain approximately 1 million pixels (3MB = 3,000,000 bytes; 3,000,000 bytes / 3 bytes per pixel = 1,000,000 pixels). However, if the image is compressed (like in JPEG format), the pixel count could be higher while still being 3MB in size.
