# 9 Graphics With Frills

In this section we describe a few options for included graphics.

## 9.1 ALT Text

### ALT Text for Images

The HTML ALT option provides some alternative text if the graphic fails to load, which also, in some browsers, appears as a tool tip. To get this in our HTML document, modify the code given in Section 8.2 so that the appropriate line reads:
 \html{\htmladdimg[ALT="Your ALT text"]{../graphics/graph.jpg}}


Note that in general any valid HTML markup can go in the optional argument for \htmladdimg.

### ALT Text for Equations

The ALT text can also be set in equations. By default LATEX2HTML uses the LATEX source of the equation as the ALT text , which is pretty meaningless for most readers, so it is useful to either suppress it by specifying a null string, or to give something more helpful. In the case of equations, the ALT text is specified with a \htmlimage command (rather than with a \htmladdimg command) as in the following example:
$$\htmlimage{ALT="An important equation"} \label{eqn1} e^{i\pi}=-1$$

which gives:
 (1)

If you are reading this in Internet Explorer, holding your mouse over the equation should produce a tool tip An important equation'.

## 9.2 Borders

To stick a border round the image -- in both the PDF and HTML versions -- we modify two lines of the code in Section 8.2 as follows:

\latex{\fbox{\includegraphics{graphics/graph.jpg}}}



## 9.3 Scaling

Sometimes it is useful to scale images. To make the image four inches wide in both the PDF and HTML versions, for example, use:

\latex{\includegraphics[width=4in]{graphics/graph.jpg}}}



Unfortunately it does not seem possible to get LATEX2HTML to correctly generate a WIDTH="50%" type of construction, which would match the scale=0.5 option of \includegraphics. This is presumably another bug or oversight.

## 9.4 Caption Placing

In the PDF version, the caption will be above the image if the \caption comes before the \includegraphics; otherwise it will be below. LATEX2HTML is not sensitive to this, however.

## 9.5 Example

As an example, Figure 9.5 is a scaled, boxed image with ALT text. Further examples may be found in example.tex.

Note that the \includegraphics and \htmladdimg commands have many other useful options; they are explained in the hyperref` and LATEX2HTML documents.
