Venables was released on licence in 2001 after serving just eight years for the horrific murder of James Bulger
But he returned to prison last November after he was caught with the pictures.
Today he pleaded guilty to having indecent images of children and having a paedophile manual.
The court heard how police discovered the so called paedophile manual – titled “Jazz Guide” – aimed at teaching how to have sex with children “safely”.
As he was being taken to a police station, the court heard that Venables admitted he had “let people down”.
He said: “This is my own fault. I have let people down again.
“I have had stupid urges, inquisitive. I’m not going to be seeing this for a lot of years.
“It’s not going to be a slap on the wrist for me.”
Prosecutor Louis Mably QCMably said: “The manual is a disgusting and sickening document which falls far below any recognisable standard of morality.”
He added Venables had software on his computer to browse the dark web.
