<th> adds a header for some column(s) of a table.
●
<td> adds a piece of data for some row(s) and column(s) of a table.

<thead> defines a set of table header rows. The intent of this tag is to provide a set of
header rows for each printed page. While viewing the page in a browser, the header has
no more effect than the <th> tag. What it provides for the designer is a more logical
breakout of the data. The table’s header area is easily recognizable, since it appears
between the <thead> start and end tags.

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.
