Hmm.  One thing that I've seen suggested elsewhere that may help is to  
forget about trying to fill the frame with the object in question,  
move the camera further away, and then crop the final image to  
appropriate borders.  A modern digital camera has plenty of pixels to  
be able to afford post-exposure cropping, and actual depth of field is  
a function of distance from the lens as well as f-stop and focal length.

(This is usually advice to people who end up with out-of-focus  
pictures because they have no macro mode at all, and an in-focus  
picture with 1MP is more useful than an out-of-focus 8MP image,  
especially if it's going to be shrunk to a webpage anyway.  It may not  
be applicable to your situation.   Then again, it might be worth a try.)
