With Magic Set Editor, you really don't have to worry about it being too big or anything like that. There's a built-in tool that allows you to resize the image.
With selection tools available in Photoshop like: Lassso tools, Magic Wand, Quick selection. With selected pixels you can do whatever you want: delete them, change or mask or create new layer from selected pixels.

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.
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
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 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".
For a 12 x 12 inch print your ideal image resolution dimensions should be 3600 pixels by 3600 pixels. At a minimum your dimensions should be 1800 by 1800 pixels. Larger mega pixel producing cameras are often better when you want to crop your image down to smaller sizes.
if we have the more pixels the resoultion will be more high
Resolution dependent is an image that is composed of a particular amount number of pixels. The quality of the image that is produced depends on the amount of pixels.
The image resolution of a picture is broken into pixels. The amount of pixels in the picture depends on the size of the print. There are approximately 100 pixels per inch in a picture.
