Casey Anthony cried, dabbed her eyes with a tissue and looked away as pictures of her 2-year-old daughter Caylee's skull were displayed in an Orlando courtroom.

Judge Belvin Perry warned people in the courtroom Thursday morning that graphic photos would be shown. He asked anyone who might become queasy to leave during a short recess before prosecutors called a crime scene investigator from the Orange County Sheriff's Office.

Jurors viewed a series of photos depicting the wooded area near the Anthony home where Caylee's remains were found in December 2008. Duct tape was on the child's skull.

Casey Anthony is charged with first-degree murder in the girl's death. Prosecutors say she used duct tape to suffocate her daughter in the summer of 2008. The child's remains were found about six months later. The defense team says Caylee drowned in the family's above-ground swimming pool on June 16.

Earlier Thursday, Casey Anthony's brother, Lee Anthony, testified his sister told him a nanny took Caylee in June 2008 because she didn't believe Casey Anthony was being a good mother.

Lee Anthony testified his sister said that about the nanny while on bond in August 2008. According to his testimony, Casey Anthony told him the nanny, called Zanny, met her in an Orlando park and held her down with the help of her sister.

He said his sister told him "it was Zanny's opinion that Casey was not being a good mother for Caylee and that she was taking Caylee from her to teach her a lesson."

Casey Anthony said the nanny told her not to go to the police, Lee Anthony testified. According to testimony, Casey Anthony told her brother she didn't try to stop the nanny from taking the child because she was scared and "didn't know what to do."

Her brother told jurors that Casey Anthony told him the nanny had taken control of her MySpace account and was sending her messages that instructed her where to go as she searched for Caylee. He said his sister told him she had to "fulfill obligations" in order to see the child again.

According to Lee Anthony's testimony, the nanny changed his sister's password for her MySpace account to timer55. He said Casey Anthony told him the password had something to do with the number of days between the date Caylee was taken and Aug. 9, 2008, when the child would have turned 3.

"It was her hope she would get her back on that day," Lee Anthony testified.
