That brings our coverage of this sentencing hearing to a close.
It resulted in Adriana Orme, 56, from Upton upon Severn in Worcestershire being sentenced to 15 months in jail and 37-year-old Holly Le Gresley from Kidderminster being sentenced to two years.
There will be more coverage of the case on the ³ÉÈË¿ìÊÖ website.
We've also had comment from USA animal rights charity Lady Freethinker, which was also involved in tracking the network after a tip off from an activist in the UK.
Its founder, Nina Jackel, said: “The horrors being inflicted on innocent, baby monkeys for online videos are sickening, and strong actions must be taken to protect animals from such brutality at the hands of humans.
"Those involved in the creation or distribution of animal torture content for ‘enjoyment’ pose a threat to both animals and humans, and they must be held accountable."
Ch Insp Kevin Lacks-Kelly, Head of the National Wildlife Crime Unit, has said Le Gresley and Orme "acted as more than mere participants in this complex web of unjustifiable torture".
He said they had attempted to hide "behind a veil of secrecy on the internet, assuming that their participation in crimes overseas would not bring the police to their doors in the UK".
The chief inspector also said that while most investigations involving wild animals taken for human use revolved around money, in this case the group were "motivated by inflicting as much suffering as possible to these defenceless animals".
Det Ch Insp Ben Arrowsmith, who led the investigation for West Mercia Police, has said it was "without doubt one of the most disturbing cases that my team and I have ever worked on".
He also said the "hatred and deviant fascination the defendants have shown in relation to the cruelty and abuse towards monkeys is incomprehensible". 
He said the suffering endured by the monkeys involved had been "sickening and sadistic" and that it was "impossible to comprehend how anyone could find it enjoyable to watch and be part of".
Det Ch Insp Ben Arrowsmith has been speaking on the steps of the court.
He described it as a landmark case.
He said: "It's the first time in British legal history that charges relating to animal cruelty have been brought for offences that took place abroad, where the offenders are in the UK."
Tributes were paid in court to the charity Action for Primates for its work in bringing Orme and Le Gresley to justice.
Speaking after the sentences, spokesperson Sarah Kite said: "Anyone involved in this type of behaviour must be held to account, and others need to know that such extreme cruelty and depravity will never be tolerated.
"We hope these sentences will deter others from becoming involved in these perverted and sadistic activities.''
Police in Indonesia also arrested two torture suspects.
Asep Yadi Nurul Hikmah (pictured) was charged with animal torture and the sale of a protected species and sentenced to three years in prison.
M Ajis Rasjana was sentenced to eight months - the maximum sentence available in the country for torturing an animal.
This investigation went beyond the two women from Worcestershire.
Last month one of the ringleaders was sentenced to three years and four months in prison.
Mike Macartney, 50, who used the alias The Torture King, pleaded guilty in the US state of Virginia to conspiracy to create and distribute animal crushing videos.
He was one of three key distributors identified by the ³ÉÈË¿ìÊÖ Eye team in their year-long investigation.
The reporting led to a nationwide criminal investigation in the US by the Department of ³ÉÈË¿ìÊÖland Security, the FBI and the US Fish and Wildlife Service.
The judge mentioned Le Gresley's knowledge of the jail time she could face if she was caught.
Following the ³ÉÈË¿ìÊÖ investigation, West Mercia Police officers spent more than a year recovering thousands of files from 20 devices owned by the women.
They were assisted by Action for Primates, a UK-based advocacy project.
Below is just one of the conversations involving Le Gresley, who used the nickname The Immolator.
Image source, West Mercia PoliceSpeaking in August, Ch Insp Kevin Lacks-Kelly, head of the UK National Wildlife Crime Unit, said the case had been the worst he had dealt with during his 22 years as an officer.
"We’ve seen the worst that humanity can bring," he said.
"I can't offer any rationale or reason as to why somebody would want to go to the levels that they went to, to persecute, kill, harm and maim these innocent animals."
Both women have now been led back to their cells.
We're expecting a comment from West Mercia Police officer outside the courtroom now.
We'll bring that to you when we get it.
The judge said he could not give suspended sentences after their "deplorable, abhorrent and sadistic behaviour".
He said their offences went against any sense of compassion.
The judge said the maximum jail sentence was reduced because of the guilty pleas.
He told both women: "In my judgement I'd be failing in my public duty by suspending the sentence.
"Such behaviour should not be tolerated and must be marked with immediate imprisonment.
"The gravity of your offending outweighs the other factors."
Le Gresley has been jailed for two years, while Orme is jailed for 15 months.
In explaining his thinking, Judge Burbidge rejected suspended sentences.
The judge has turned to Orme now - he noted the "moving tributes" paid to her and that she had cared for a rescue dog.
He also noted her mental health conditions, but did not accept she was isolated from people as had been claimed.
The judge said both defendants had high culpability factors from prolonged and serious cruelty, and sadistic behaviour.
He said certainly Le Gresley had played a leading role.
After listing some of the horrific torture inflicted on the monkeys, the judge told Le Gresley the crimes she had committed carried a maximum sentence of five years, as she herself had noted in her online conversations.
He also told the court there must be "some level of deterrent".
The court heard Le Gresley has described how she believes she now has post-traumatic stress disorder from watching the videos.
The judge has been recalling, in detail, some of the torture inflicted on monkeys in the videos.
One monkey died after being tortured for around 10 minutes, he said.
Because of the nature of the offences, we will not be repeating the detail on this live page.
Le Gresley "in effect became an archivist for the group", the judge said.
He told her: "You offered to help catalogue a user's collection.
"You boasted about the amount of videos and images you possessed."
