In GNU/Linux, LibreOffice use ~/.config/PROGRAM/4/user/gallery as the default path for inserting image. I am just not sure this directory would be used by user as a place for storing their images/pictures. Would if someone consider to change this directory to a more common one .e.g ~/Pictures in GNU/Linux or C:\Windows\Users\Pictures (Not sure this is the right path) in Windows?
Sounds like a good idea, I assume modern OSes have a way to query the Pictures directory, but not sure how widespread the feature is, and how it can be done. The previous location should also be remembered when using multiple times, bug 126875 is on that (merging the two bugs could be considered).

In a recent master build on Ubuntu 20.04, the default location is home/username/Documents, which is an improvement: Version: 7.6.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: ec2f1d73936c9d8cee83c0887170e9ecb8f044ba CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3 Locale: en-AU (en_AU.UTF-8); UI: en-US Calc: threaded On Windows 10, it's Users\username\Documents as well: Version: 7.6.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: 9b46020c262045aed0beace4708565235c2523cc CPU threads: 4; OS: Windows 10.0 Build 19045; UI render: Skia/Raster; VCL: win Locale: en-GB (en_GB); UI: en-GB Calc: threaded In both cases, the Pictures directory could be a better choice.
