Adding full page figures in Latex, how?

\begin{figure*}[tb] 
\centering
 \makebox[\textwidth]{\includegraphics[width=.9\paperwidth]{./fig/fig5.eps}}
\caption{The SAP data model based on an UML class diagram: classes and relationships.}
\label{fig:Fig5}
\end{figure*}

If you also want the caption to be rotated, you can also use

\usepackage{rotating}

\begin{sidewaysfigure}

That also eliminates the need for using angle=90 or something like that

\begin{figure}[hbtp]

• h = here
• b = botom
• t = top
• p = page of floats

Algorithm will try the current position in document first, then bottom, then top and then on a seperate page. If you just specify 'h' you will force placement where the figure command is in the document. The order is encoded by you -- i.e., you could specify ptbh which would force a reverse order of evaluation.

p.s., I would strongly recomend anyone using latex to use lyx. Its just as powerfull as straight latex but its wysiwyg and you can drop to tex anywhere you want.
