One of the WYSIWYG Editor's most useful features is its ability to resize an image while maintaining its original quality and resolution. You can resize an image as many times as you want to and you won't lose any quality. The WYSIWYG Editor bases each new size on the original image file and not on the last change made to the height and width.
There are three ways to resize images in the WYSIWYG Editor:
Drag the image borders: You can use your mouse to drag the borders that surround the image to visually enlarge or reduce its size. This method is quick and convenient if you do not need to resize the image to an exact measurement.
Increase or decrease by percentages: You can increase and decrease the size of the image by a percentage measurement (percent refers to the window size, with 100 percent width or height equaling the window's width or height). The image automatically resizes in proportion to the size of the viewer that displays it. If you want an image to display at the full width of the window (100 percent), this is a useful way to resize an image.
Set pixel values: You can increase and decrease the image by pixel values. Pixels measure the dimensions of the image in screen pixels.
Note: When you resize images, select the Maintain aspect ratio check box. This keeps width and height settings proportional so that the image is not distorted.
