https://help.libreoffice.org/7.2/en-US/text/shared/01/06050400.html is help page for: Format > Bullets and Numbering > Image tab.
1. "Link graphics" is mentioned as a control, but does not appear in the dialog.
2. "Add and Size" button in dialog is not mentioned on help page (or other help pages, afaik).
Actually I could not make the "Image" tab work. Clicking "Add and Resize" was supposed to include a new image in the "Selection" area. Then clicking it was supposed to apply the image as the current graphics for the bullet. However none of this worked.
The only way I could used a graphics file as a bullet was through the Customize tab, choosing "Graphics" in the "Number" drop-down list and then "From file" in the "Graphics" option.
Could you please confirm this wrong behavior in the Image tab?

It was possible with both version 7.2.5 and 184.108.40.206.alpha to use the Add and Resize button to add "bullets", but no indication of any resize.
1. Click on Add and Resize (on Image tab in Bullets and Numbering dialog)
2. File Picker opens.
3. Select a graphics file.
Result: gets added to selection (but you have to look around. It seems to be alphabetic -- but then maybe also sorted by file type).
4. Select the added image.
Result: "bullet" is created with this image.
Additional "problem" or improvement -- the file picker should be limited to graphic files.
