As writer images (and frames) are not standard objects like in other modules, the Format > Name command (.uno:NameGroup) doesnt work with it while it should. The command should work with all objects, where it is possible to name them, just like how Format > Description (.uno:ObjectTitleDescription) works with all objects.
Gulsah Kose committed a patch related to this issue.
It has been pushed to "master":
tdf#103268 Activate editing object name function for writer images.
It will be available in 5.3.0.
The patch should be included in the daily builds available at
http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More
information about daily builds can be found at:
Affected users are encouraged to test the fix and report feedback.
Thanks Gulsah for taking this on. Is it possible to also do if for frames, as mentioned in the description, or should i open a new bug for that?

Yes, this patch works for frames too.
Verified with version 5.3.0: Renaming of images and frames is now possible with:
Format > Name...
Hence I closed this bug.
