A heavily pregnant woman has been jailed for four years after hatching "a wicked plot" to frame an innocent ex-lover.
Vindictive Rebecca Tooze, 35, arranged for a vile porongraphic photograph to be slipped into the parked car of an ex-boyfriend, against whom she held a grudge.
Then boyfriend, long-distance lorry driver James Willis, 37, made an anonymous phone call to the police in September 2010.
However the victim had already discovered the revolting image and called the police himself.
Police uncovered the evil plot by tracking forensic evidence to the home of Willis in Manorfield, Ashford. There they discovered he had printed pornographic images from his computer, including the one of a naked toddler in a bondage harness, and found DNA belonging to Tooze.
Prosecutor Paul Valder said a search of the house also revealed a script - in Tooze's handwriting - of the anonymous phone call to police made by Willis.
Tooze dreamed up her "prolonged, malicious and perverted plot " after her relationship with the ex-lover "turned toxic".
Now Tooze will give birth to her child in prison after admitting conspiring to pervert the course of justice - on the day her trial was expected to start.
The victim - who cannot be named for legal reasons - faced losing his career and his liberty if her plot had been successful, Canterbury Crown Court heard.
In jailing Tooze and Willis each to four years in prison, Judge Adele Williams told them: "This was truly wicked behaviour by both of you and one of the worst examples of perverting the course of justice there could be.
"You planted child pornography in the back of the car of an innocent man. You two hatched the plot to discredit him."
Tooze, she said, had acted out of "calculation and malice and selfish self-interest." Tooze remained impassive throughout the hearing but her defence said she had been diagnosed with Histrionic Personality Disorder.
The judge revealed that Tooze had previously made allegations of rape against her ex-lover - which had also been rejected by a court.
"If this plot have succeeded you would have ruined his life," she added.
