--- Comment #18 from Christophe Strobbe <c_strobbe-fdo at yahoo.co.uk> ---
Since I reported the bug, I though I should recheck it.
I created some slides in LibreOffice Impress 7.1.4.2 on Windows 10 and exported
them as PDF using two sets of options: once with just "Tagged PDF" (but no
PDF/UA) and once with both "Tagged PDF" and "PDF/UA" enabled. This did not
result in a different treatment of text alternatives for images. I found the
following:

- When an image has only a Title but no Description in Impress, the Title gets
exported as a text alternative. (The length of the Title does not seem to make
a difference, i.e. also short Titles get exported as text alternatives.)
- When an image has only a Description, the Description gets exported as a text
alternative.
- When an image has both Title and Description, the Title and the Description
get combined into a single text alternative (i.e. concatenated with ' - '
between them). I don't know what to advise in this scenario: either mapping
Impress's Title to PDF's title (in Adobe Acrobat) or dropping Impress's Title
altogether if there is a Description.

In response to Manuel Razzari's comment: Neither ODF 1.2 nor ODF 1.3 (released
in April 2021) provide a feature that allows you to explicitly mark an image as
decorative. See my comment on bug 143311:
