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.
+The steerable parameter {\tt IOJpeg::refinement\_factor} determines whether the
+resulting JPEG images (of same size as the underlying grid) should be refined
+by a certain factor. If refinement is enabled ({\tt IOJpeg::refinement\_factor} $>$ 1) an interpolation will be done to enlarge the images to the requested size. For this case, a thorn providing local interpolation operators must be activated (eg. thorn {\tt CactusBase/LocalInterp}).

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).
