[tex4ht] converting all displaymath to images with make4ht

Hi Benjamin,

You can also try tex4ebook. It converts to ePub directly. It is based on 
make4ht, but it also saves some metadata and TOC.

Display math is converted to pictures by default, without need to use 
pic-{something}. For example the following example converts to picture 
with make4ht without any options:


\documentclass{article}
\begin{document}
\[ \sum\displaylimits_{i=1}^{3} \sum\displaylimits_{j =1}^{3} p\left(F_{i} , E_{j}\right) = 1 \]
\end{document}

It is possible that you use some package that changes the default 
behavior. Could you please post a full MWE?

Best regards,
Michal
