The below file directory has bitmap files : /usr/lib/libreoffice/basis3.3/share/template/wizard/bitmap I noticed that there are also gif files in the same directories with a better compression ratio. I think that converting bmp files in gif, png or mng would save space.

Jérôme, thank you for reporting this. Could you please attach to this bug both one of the .bmp files you found, and that file converted into a format that will both preserve the image quality and lower the file size?
Created attachment 56470 [details] /opt/libreoffice3.5/share/template/wizard/bitmap/XML-Import_2-1.bmp the orginal image shiped with libreoffice
Created attachment 56471 [details] /opt/libreoffice3.5/share/template/wizard/bitmap/XML-Import_2-1.png the png version which size is only 18% of the original image
Now in 6.3 we have only 10 .bmp files. Its overall wight is 33kb. May be this bug might be closed?
Created attachment 149923 [details] dpkg-deb --contents lodevbasis6.3-core_6.3.0.0.alpha0-1_amd64.deb | grep -i 'bmp$' | awk '{ print $3"\t"$6 }' We can convert the 2 biggers files into png : end.bmp, report.bmp.
Hmm... I don't see how they are used at all - there seems to be no references to them throughout the code. Or are they referenced from some template ODFs?
