13. Using image and maps

13.1. Adding an image

To insert an image, choose Image from the Insert menu, click the image button, or use the keyboard

shortcut (Ctrl-h Ctrl-i). The resulting dialog lets you enter

• the file name

• the alternate text (alt attribute) of the image

• and the position (inline, on the left side, centered, on the right side)

Note: the alternate text is mandatory. You must provide a short description of the image in the

corresponding field or confirm twice.

To help find an image file you can enter a filter, and use the filter button, and the dialog will list only the

files that match your pattern.

To provide a long description for an image presenting complex information, you should do so in a

separate document and link it by providing the URI as a longdesc. This command is also available on

the Attributes list.

13.2. Replacing an image

If an image is selected (do so by dragging over the image) when opening the image dialog, the selected

image is then replaced by the new image.

13.3. Resizing an image or a map area

After you have inserted an image or defined an area within an image map, you may need to resize it.

To resize the image or map area directly on the screen:

1. Select the image or the area of the image map to display handles.

When you click on an image, Amaya selects the left or right border of the image to let you

insert a text before or after the image.

To display image handles, you have to:

◦ either select a border and press Esc or F2,

◦ or drag over the image

2. When selecting a handle with the left button of the mouse and moving the mouse with the left

button down you are able to resize the image or the area as you want.

◦ Corner handles let you resize both the width and the height.

◦ If the Shift key down, the ratio between the width and the height of the image is kept.

◦ Other handles let you resize either the width or the height.

You may also edit attributes.

13.4. About alternative text and long descriptions

Without useful alternate text for images, many web pages become difficult or even impossible to

navigate, and users are left "feeling their way in the dark."

To prevent this problem, you must provide alternate text for elements such as images and other

multimedia objects. The alternate text is usually presented instead of the image by a browser with a voice

output system, or on a Braille display used by many people who are blind. It is also common for users
