1. pic-array, pic-eqnarray, pic-tabbing, pic-tabular

These parameters ask for pictorial, instead of tabular, representations for the specified environments.

[Picture] 
       \documentclass{article}
          \usepackage[html,pic-tabular]{tex4ht}
       \begin{document}
       
       \begin{tabular}{|r||r@{--}l|p{1.25in}|}
       <.entries of tabular.>
       \end{tabular}
       
       \end{document}

2. pic-displaylines

This package parameter asks for a pictorial representation to the outcome of the \displaylines command.

3. no-halign

This package parameter asks TeX4ht to avoid translating \halign tables into html. The system is not capable of dealing with all cases, and it might even crash when unfamiliar cases are encountered.

4. pictex

This parameter notifies TeX4ht that the document contains PicTeX pictures.

5. jpg, png

These package parameters ask for extension `jpg' and `png', respectively, instead of `gif', for automatically created files of pictures.
