First of all you should upload a profile photo which will show on your page and on your account. This must be a safe-for-work image, showing yourself without showing nipples or genitalia. Nudity is fine but nipples and genitalia must be covered.

The same rules apply when you upload a picture for emails or offline photos.

When you upload an image to be used in marketing, then any nudity is fine but the image should be a very good one, hopefully looking very professional, as it will highlight you far better.

Images for 'away' or 'be right back' screens should be set up with the same in mind, showing a good image which explains you will be back soon. This can be with or without you in the image.
