5 Enter values in the Alternate Text and Long Description text boxes, and click OK.
• In the Alternate Text box, enter a name or brief description for the image. The screen reader reads the information
you enter here. You should limit your entry to around 50 characters. For longer descriptions, consider providing a
link, in the Long Description text box, to a file that gives more information about the image.
• In the Long Description box, enter the location of a file that displays when the user clicks the image or click the
folder icon to browse to the file. This text box provides a link to a file that is related to, or gives more information
about, the image.
Note: You can enter information in one or both text boxes depending on your needs. The screen reader reads the Alt
attribute for the image.
Note: If you click Cancel, the image appears in the document, but Dreamweaver does not associate accessibility tags or
attributes with it.
6 In the Property inspector (Window > Properties), set properties for the image.

Inserting images tutorial
Set image properties
The Images Property inspector allows you to set properties for an image. If you do not see all of the image properties,
click the expander arrow in the lower-right corner.
1 Select Window > Properties to view the Property inspector for a selected image.
2 In the text box below the thumbnail image, enter a name so you can refer to the image when using a Dreamweaver
behavior (such as Swap Image) or when using a scripting language such as JavaScript or VBScript.
3 Set any of the image options.
W and H The width and height of the image, in pixels. Dreamweaver automatically updates these text boxes with the
image’s original dimensions when you insert an image in a page.
If you set W and H values that do not correspond to the actual width and height of the image, the image may not
display properly in a browser. (To restore the original values, click the W and H text box labels, or the Reset image size
button that appears to the right of the W and H text boxes in entering a new value.)
Note: You can change these values to scale the display size of this image instance, but this does not reduce download time,
because the browser downloads all image data before scaling the image. To reduce download time and to ensure that all
instances of an image appear at the same size, use an image-editing application to scale images.
