The family portraits were taken in a hospital room in the Bahamas two days after the birth of Anna Nicole's daughter and hours before her 20-year-old son was found dead.
Photo agency Getty Images sold the photos to In Touch magazine for $400,000 after a fierce bidding war.
According to In Touch executive editor Dan Wakeford, "We purchased the photos, beating the competition.
"The photos were extremely emotive, and our readers are incredibly intrigued by this story."
Wakeford says the images show "a perfectly healthy young man."
While it is unclear what portion of the proceeds will go to Anna Nicole, a source tells Us Weekly magazine that the devastated star sold the pictures in order to pay for her son's funeral.
The source says, "She needs the money."
Getty Images claims that a portion of the profits from the sale of the photos will go to a charitable foundation to be set up in Daniel's name.
His body remains at Butler's Funeral Home in the Bahamas and won't be released to the family until the investigation into his death is complete.
