Images; Links - Avaya 4600 Series Administrator's Manual

<tfoot> defines a footer for a table. This tag can contain multiple rows. Like the <thead>
●
tag, the intent of this tag is to provide a set of footer rows for each printed page. Viewing
the page in a browser has no additional effect. And like the <thead> tag, this tag provides
a logical breakout of the data for the designer.
<colgroup> defines a column group. It can be used as a single definition of identical
●
columns or as a container for dissimilar columns. The span attribute defines what columns
are parts of each group.
<col> controls the appearance of one or more columns within a column group.

Images

The 4630 IP Telephone Web Browser handles both GIF and JPEG image formats. No other
image formats, included animated GIFs, are supported. Note that images take up a large
amount of memory compared to text and that updating the display can be an issue. For these
reasons, we recommend keeping images to a minimum.
The image tags that can be used on the browser are:
<img> displays an image.
●
<map> display a client-side image. Client-side images have shaped regions called areas.
●
These areas are tied to URLs or ECMAScript functions. Clicking on an area in a region
executes the ECMAScript function.
<area> defines an area in a <map> image. Each area uses the href attribute to define a
●
URL to jump to, or an ECMAScript to execute when that area is clicked.

Links

As of Release 1.8, the 4630/4630SW IP Telephones support dialing from hyperlinks. To dial
from a link, a given link's href attribute value must of the form tel:nnnnn or
javascript:dial('nnnnn'). Selecting that link passes the characters nnnnn to the 4630/4630SW
Phone application for direct dialing.
Hyperlinks are the heart of the Web browser's power. The link allows the user to:
click text or an image to jump to another Web site,
●
click text or an image to jump to another page within this site, or
●
click text or an image to jump to another area on a page.
●
Although URLs allow you to use various protocols, use only HTTP and HTTPS for the 4630 IP
Telephone Web Browser.
