I have no problem on the mac with chemdraw files if saved as a pict file. This can then be converted to gif by the shareware GraphicConverter. For the best effect I then set the background to transparent (from the colour setting). I have converted 100's of files this way on my IUPAC nomenclature Web pages which I will circulate details with a following message.
