Printing a photograph in a newspaper and printing a photograph in an art book will require very different image resolutions. For the newspaper 100 pixels per inch is OK for the art book 600 or more. So if your image is 5 * 8 inches the newspaper picture should be 500 * 800 pixels or 400 000 pixels, the art book greater than 15 million pixels.
1 Megapixel = 1,000,000 pixels so to find out how many megapixels, divide the number by 1,000,000: 54,000 / 1,000,000 = .054 megapixels or not very much at all, that's an image that is better suited for websites rather than printing.
If you mean bigger the 1 megapixel is bigger. If you needed a bigger image for printing or to be shown on a bigger screen for example. If you needed a smaller image (for instance) the 68000 pixels may suit your purpose better.
When a person refers to image data, they are most likely referring to the internal code of a picture file that tells the computer information it needs to display the image, such as (but not limited to) what color the pixels in an image are, how many pixels an image has, and what image type it is.

Any digital image is made of pixels - the more pixels in the image, the greater the detail and the greater the clarity.
If the image is 800 pixels by 600 pixels at 240 pixels per inch, then the image size is (800 / 240) by (600 / 240) or 31/3 by 21/2 inches.
pixels
pixels do not go into megabytes. Kilabytes do. There are 1024 kilabytes in one megabyte. 1024 megabytes in one gigabyte and 1024 gigabytes in one tetrabyte.
Digital image printing can be done at home, at many retail stores and websites. Among the stores and websites are Walmart, Target, Digital Image Printing, and Office Depot.
An image is made up of pixels, or tiny squares that each have a designated color. the pixels are normally so small that you don't see them. However, sometimes a picture looks blurry when resized. That blurry image is a pixelated image.
Image size can refer to either its file size or the width x height of the image. Resolution is used to specify how many dots per inch (dpi) are used when plotting an image - for example a 1720x1720 pixels image displayed at 172dpi will cover 10'x10'.
Image resolution is usually expressed by giving the dimensions of the image in pixels. The size of an image that is 640 pixels wide and 480 pixels tall would be expressed as 640x480. 640x480 is read as "six forty by four eighty".
