Two alternatives:

1. Uncomment the first 4 records of the <default>...</default> 
   segment in tex4ht.env 
      http://www.cse.ohio-state.edu/~gurari/TeX4ht/tex4ht-env-unix.txt
   by removing leading spaces from those records.

2. Disable the <default>...</default> segment and activate the
   <netpbm>...</netpbm> segment. For the deactivation rename the
   `default' tag and end tag.  For the activation introduce spaces
   before the `netpbm' tag and end tag.
