How Do I Change the Number of Pixels in a Picture?

The resolution of a picture is the number of pixels, such as 800 by 600. Changing the resolution or size of a picture may be needed when inserting it onto a Word document or adding it to the body of an email message. Many image programs are available to change a picture's resolution. To do this, open the picture file in a photo-editing program such as Windows Live Photo Gallery.
