That's good to hear!

One thing I noticed is that when you use uppercase name of the image extension (PNG in your case), normal TeX4ht image handling is not used, and you will get an unnecessary call to Dvipng. It is unrelated to your original problem, but I think you should know about it.

excluding package caption resolves the issue.

For me, the issue is closed.

Thank you:)

Hello Michael,

can you please post a full document where this happen? It can be caused by some package. The following MWE works correctly with current TeX4ht:

% \usepackage{caption}
\caption[BLA]{real caption}

I am setting a figure with caption incl. optional argument, and then, in the HTML, the optional argument is not only placed into the LOF, but BUG: also at the figure itself.

The caption is set in my tex source like:

\caption[BLA]{real caption}

The figure is set in the HTML like (BUG)

[real caption]

The raw HTML snippet:

<!--l. 34--><p class="noindent" > <hr class="figure"><div class="figure"


<!--l. 34--><p class="noindent" ><img
src="FILE.PNG" alt="PIC"


<div class="caption"

Many thanks, Michael :)
