Hello, Using Mathematica 7.0, how can I take an image and give it a position and scale, so that it can be combined with other graphics? Here's what I am trying to do: I would like to have an image map of the moon as the background for my plot or contour plot. I want to be able to plot points by their lat,lon positions and have them appear at the correct points on the map. I came up with a hack to do this by rasterizing the plot using Image[] so that it is the same resolution as the moon image, and then combining the two images. (I found a similar technique here: http://mathgis.blogspot.com/2007/12/fun-with-image-overlay.html) The problem is this does not work if the plot has Axes->True, because some space is used for the axes, so the coordinate systems don't match exactly anymore. I really would like to have both Axes and the image together. Is there a good way to do this? Thanks, Dave
