Hi. Can you show me the corresponding message in WhatsApp?

[mruepp]

Should be this. But the time is off (10:20 in html vs 11:43 in chat) it is a Video I can not start...

Also, btw, is there a way to implement lazy loading? I have chats back to 2014, they are 100-200MB large HTMLs which are nearly unable to load...

There is no lazy loading but you can use --size 0 to split the chat into multiple files.

Thank you, is there documentation of --size? --size 0 is kind of counterintuitive. What does it mean?

> wtsexporter --help
...
  --size [SIZE], --output-size [SIZE], --split [SIZE]
                        Maximum (rough) size of a single output file in bytes, 0 for auto

Any suggestions are welcome!

Btw, docs are either located in the Wiki or in the help menu.

I'm not a web developer but I did some quick research and maybe all we need to get the lazy loading is add a tag to the images as documented here: https://www.w3schools.com/tags/att_img_loading.asp
Only Safari doesn't handle this tag.

<img src="Media/Profile\33610007857-1665000879.thumb" loading="lazy" class="avatar">

Also while commenting on things that I don't really know, maybe you could consider using the base tag in your HTML? Maybe you have a reason not to use it or maybe it's just me but my links are pretty long like this:
<a href="AppDomainGroup-group.net.whatsapp.WhatsApp.shared/Media/Profile\6590002603-1700006881.thumb"><img src="AppDomainGroup-group.net.whatsapp.WhatsApp.shared/Media/Profile\6590002603-1700006881.thumb" onerror="this.style.display='none'" class="avatar"></a>
with the base tag like this:
<base href="AppDomainGroup-group.net.whatsapp.WhatsApp.shared/">
you should be able to shorten the URLs to this:
<img src="Media/Profile\33610007857-1665000879.thumb">
