I extracted the content of the LibreOffice_7.6.3_Win_x86-64.msi archive (345MB) with msiextract. This main MSI archive installs the below file : share/config/images_helpimg.zip The content of this zip file looks like the content of the below directory : help/media/helpimg If this file can be deleted, it would save roughly 1 MB into the main MSI archive.
It' not unused, these are images used by the local help. From Repository.mk: $(if $(ENABLE_HTMLHELP),\ helpcontent2_html_dynamic \ helpcontent2_html_media \ helpcontent2_html_icon-themes \ helpcontent2_html_static \ and in helpcontent2/Package_html_media.mk lists the images/example files. Grepping for their name shows that these are referenced from help files, for example: gabor@voldemort:~/src/core/helpcontent2$ git grep files/scalc/conditionalformatting.ods Package_html_media.mk: files/scalc/conditionalformatting.ods \ source/text/scalc/06/calcsamplefiles.xhp: <paragraph role="paragraph" id="par_id591563765191143" localize="false"><object data="media/files/scalc/conditionalformatting.ods" id="ods_id61521525603534" type="application/vnd.oasis.opendocument.spreadsheet" /></paragraph> gabor@voldemort:~/src/core/helpcontent2$ git grep what-if.png Package_html_media.mk: helpimg/what-if.png \ source/text/scalc/guide/multioperation.xhp:<image id="img_id1621753" src="media/helpimg/what-if.png"><alt id="alt_id1621753" xml-lang="en-US">what-if sheet area</alt></image></paragraph> gabor@voldemort:~/src/core/helpcontent2$ git grep swh00179.png Package_html_media.mk: helpimg/swh00179.png \ source/text/shared/guide/tabs.xhp:<image id="img_id3153192" src="media/helpimg/swh00179.png" width="0.2228inch" height="0.2228inch"><alt id="alt_id3153192" xml-lang="en-US">Icon</alt>
If it is a source file, then it shouldn't be into the main MSI archive.
This file is also in : libobasis7.6-images_7.6.4.1-1_amd64.deb
I understand share/config/images_helpimg.zip is never used at runtime. The files inside this archive are duplicated outside this archive. Since "share/config/images_helpimg.zip" is a "source" file, why is it packaged into the target help archive ?
Thanks for pointing that out! It’s important to keep installation packages clean and organized for smoother deployment.

Maybe Olivier knows something about this.
The old Help system is still built for backward compatibility with some extensions, and needs these images. => NOTABUG or WONTFIX
