-
- <h3 id="Adding">Adding an Image</h3>
-
- <p>To <em>insert</em> an image, choose <strong>Image</strong> from the
- <strong>XHTML</strong> menu, click the <strong>Image</strong> <img
- src="../../resources/icons/22x22/XHTML_Image.png" alt="Image button" />
- button, or use the keyboard shortcut (<code>Ctrl h</code> <code>Ctrl
- i</code>). The resulting dialog lets you enter the file name and alternative
- text (<strong>Alt</strong> attribute) of the desired image.</p>
-
- <p class="Note"><strong>Note</strong>: the alternative text is mandatory. You
- must provide some text in the corresponding field.</p>
-
- <p>To help find an image file you can enter a filter field, and use the
- filter button, and the dialog will list only the files that match your
- pattern.</p>
-
- <p>To provide a long description for an image presenting complex information,
- you should do so in a separate document and link it by giving the URI as a
- <strong>longdesc</strong>. This command is also available on the
- <strong>Attributes</strong> list.</p>
-
- <h3 id="Replacing">Replacing an Image</h3>
-
- <p>If an image is selected (do so by dragging over the image) when opening
- the image dialog, the selected image is then <em>replaced</em> by the new
- image.</p>
-
- <h3 id="About">About Alternative Text and Long Descriptions</h3>
-
- <p>Without useful alternative text for images, many web pages become
- difficult or even impossible to navigate, and users are left "feeling their
- way in the dark."</p>
-
- <p>To prevent this problem, you must provide alternative text for elements
- such as images and other multimedia objects. The alternative 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.áIt is also common for
- users with low-quality connections to request the alternate view, because
- text is transmitted much faster than images.</p>
-
- <p>The alternative text should replace the image in function as well. For
- example, if you use the image as an icon that links to a reference point,
- then the title of the reference itself is a good alternative text.</p>
-
- <p>There are cases where an image is used for purely visual effect, and does
- not add any information value to the page. In this case, it is appropriate to
- use a blank alternative text, although you must still define it.</p>
-
- <p>When the image conveys important information that is not available from
- the text of the document, you must provide a description of the information.
- The <code>longdesc</code> option in the <strong>Attributes</strong> list
- enables you to link a description to the image. This description can be a URI
- (a separate document), or named part of the current document.</p>
-
- <p>To view how a page might be presented without the images, use Show
- Alternate (<span class="Link0"><strong>Views >Show
- Alternate</strong></span>). If the page is spoken by a voice output system,
- then the alternate view might simply be read out.</p>
-
- <h3 id="Using1">Using client-side image maps</h3>
-
- <p>Amaya enables you to use client-side image maps.</p>
-
- <p class="ProcedureCaption">To activate an area in an image map</p>
- <ul>
- <li>Double-click on the area within the image. Amaya finds the URI
- associated to this area, and opens it in the browser.</li>
- </ul>
-
- <p class="ProcedureCaption">To display the existing areas within an image
- map</p>
- <ul>
- <li>Select <strong>Show Map Areas</strong> from the <strong>Views</strong>
- menu.<br />
-
- <p class="Note"><strong>Note:</strong>áá You can also display existing
- areas directly from the keyboard by clicking <code>Ctrl v
- Ctrl</code><code>t</code> (<code>Ctrl u Ctrl t</code> on Windows
- platforms).</p>
- </li>
