Source for downloading extra bitmaps?

[appreciatethehelp]

Mac OSX Mojave 10.14, Libreoffice 6.2.5.2

Hi everyone, upon checking out the bitmaps in LO, I noticed there is only a small range; does anybody know where I might be able to download some extra bitmaps?
I want to use the bitmaps initially to designate table cells that should be ignored/not filled out.

Thanks.

Bitmaps for the gallery? What purpose are the bitmaps for? Some “extra bitmaps” (images of different specification) are part of some extensions.

• https://extensions.libreoffice.org/extensions/openclipart-org-integration (be aware that openclipart.org was hacked and is off-line for months)
• Die Live-Seiten der ProOO-Box. (see here: Cliparts part)
• Download clip art (answer of @RGBes of 2017, still up-to-date)

For better replies EDIT your question, please.

I guess something like that was meant:
https://extensions.libreoffice.org/en/extensions/show/legacy-gallery-backgrounds

I would be interested in more bitmaps to fill areas as well.
