+\section{Use}
+
+Thorn IOJpeg provides 2D images from grid functions in jpeg format, these
+images are currently intended to be used for two purposes:
+
+\begin{itemize}
+
+\item{Monitoring from Web Server} Jpeg images can be directly visualised
+in the {\it viewport} provided by thorn {\tt CactusConnect/HTTPDExtra}. For 
+the images to be advertised to the Web Server the parameter {\tt iojpeg::mode = ``remove''} must be used.
+
+\item{Constructing Movies} A series of jpeg movies can easily
+ be used to construct a time series movie (e.g. using the Unix utilities
+{\tt convert} or {\tt xanim}). In this case the parameter {\tt iojpeg::mode = ``standard''} must be used.
+
+\end{itemize}
+
+Note that the parameter {\tt iojpeg::mode} determines whether a jpeg image is ccreated and kept for individual timesteps, or whether only the image from the current data is kept. Only in the second case is the jpeg file {\tt advertised} (otherwise there are potentially thousands of files advertised to e.g. the {\tt HTTPD} thorn). Also note that using the standard mode and creating jpegs every iteration can quite quickly lead to {\it inode} problems on a machine.
+
+We are planning to develop this thorn more to provide more features (eg 
+a range of 2D images from a 3D dataset, add possibility to save images for a movie and advertise current image).
