Changing Image Size in Dreamweaver

This Dreamweaver tutorial will explain how to change the size of an image on your Web page.

When images are inserted into a web page, they take up a rectangular shaped space on the page measured in pixels. The Width and Height properties can be set in the Property Inspector when the image is selected on the page.

The Width and Height properties do more than simply determine its screen size. They also help the web browser to load the page efficiently. Since the HTML of a web page downloads before any image does, if the width and height attributes of the image are missing, the browser won't know how much space to reserve for the graphic.

Web pages will load faster and more effieciently if the Width and Height attributes are specified. Whenever you insert an image into your page, Dreamweaver automatically calculates the image width and height, and enters those values into the Width and Height fields in the Property Inspector.

To Change an Image Size.

NOTE: Note that it is recommended that you change the image size in an image editing program such as Fireworks or PhotoShop, if you have one available. It is a more effiecient method of editing images than doing it in Dreamweaver, and will result in getting the exact image size you want and will also result in a smaller file size that will load faster. You may, however, modify some properties of an imageg in the Dreamweaver Property Inspector.

Click on the image in the Document window to select it. Using the handles on the side, bottom, and lower right corner, you can click and drag a handle to change the size of the image.

You can shrink a graphic by typing smaller values into the W and H fields, but doing so won't do anything to speed up the download time of the image file. Trying to make an image larger by typing a larger value in the W and H fields will result in a distorted and pixelated image that won't look very good on your page. It would be better to do this in an image editing program such as Fireworks or PhotoShop.

Another way to adjust an image's size on a web page is to grab the handles that appear when the image is selected. You can grap the handle on the right edge of the image and drag it left or right to change the width of the image. You can grab the handle at the bottom of the image and drag it up or down to change the height of the image. Or, you can drag the handle in the lower right corner to change both dimensions at the same time.

To keep the proportions the same while changing the image size, grab the handle in the lower right corner and while holding the Shif key down, change the image dimensions. Holding down the Shift key while dragging the handel will constrain the dimensions so they are in the same proportion as the original image size.
