You have set up contact sharing in Daylite via CardDAV. A contact record in Daylite has an image associated with it. The contact record is available in the Contacts app on Mac and Contacts app (on iOS) but shows up without the image.
This is a known issue where images from the contact record in Daylite do not populate in CardDAV clients. This is an issue with Apple and a bug has been filed with them for this.
