The old SVG images for Magnetic are in /graphics.dir/svg/magnetic/, where all SVG normally are kept to make them available to fen2.php. Currently this new set appears to be in /graphics.dir/MagneticPNG/svg/, which is a bit of an illogical place. So if the idea is to make it available for public use, it would probably be best to move them, or at least a copy of them, to some /graphics.dir/svg/*/ as well.
Of course one can doubt the desirability of having two practically indistinguishable piece themes there. So it might be better to just merge the sets.
