Thanks for the explanation.

I've tested that. For that to work, the corresponding data needs to be 
present in the clipboard after copying from the browser.

In a quick test, it works for me on Linux like this:

1) go to https://www.libreoffice.org/ in Firefox
2) copy the LibreOffice logo
3) open Writer
4) press Ctrl+Shift+V to open the "Paste Special" dialog
5) select "Hypertext Markup Language (HTML)" for the source format and 
press OK to paste

After that the alt text "logo" is set for the image in LibreOffice, 
which is the alt text set in HTML on the website, as can be seen with 
the wl-paste tool after copying in Firefox:

$ wl-paste -t text/html
<meta http-equiv="content-type" content="text/html; charset=utf-8"><img 
style="width:230px; height:auto;" 
src="https://www.libreoffice.org/themes/libreofficenew/img/logo.png"; 
alt="logo">

It does not work when just using Ctrl+V to paste instead of using "Paste 
Special", likely because some image format is used as the source and 
that doesn't contain the information on the alt text specified in HTML.

My test was with Firefox 115.9.1esr and a current development version of 
LibreOffice using the qt6 VCL plugin on Linux (Debian testing).
