First and foremost this group is looking for female "nude" images. This includes nude and partial nudes. This includes photos and all forms of artistic representation. However please submit to appropriately titled galleries.
Secondly, to qualify as large an image should have pixel dimensions of 1080x1920 or larger and the image should be downloadable. Aside from being preferable from a viewers standpoint, I've found this is an effective filter against most spam and stolen submissions.
Thirdly the "Large" of LargeNudes has nothing to do with the shape of models in submitted imagery. Natural beauty is to be respected here and accepted that it come in all shapes and sizes.
Fourthly, I'd like to impose some small style guidelines where submissions to be accepted should not be headless or faceless. Also implied nudes are not preferred in this particular group.
Lastly, images should be of quality. I realize this is highly subjective, but common sense should tell us when snapshots or scribbles lack interest for the groups's viewership.
