The png() graphics driver will produce bitmap graphics which should convert better to a gif. PostScript is a vector format, so there may be all sorts of things going on. Just feed png() with the width and height you want for your gif and then you wont have to resize as part of the conversion process. Also, GIFs are pretty old-tech these days, so if you could persuade your other users to switch to png files, its a big win.
