The reason is that it is being "absorbed" by the ... in the argument list, and then gets passed on both to plot (to set up the plotting region, aspect ration, axes etc) and to image. The first however doesn't understand this, hence the warning. This doesn't look hard to solve, it's basically a bit sloppy / lazy programming.
