- As it happened: 14 January 2015
- The ex-lover of paedophile Ian Watkins said she was only trying to trap him
- They had an on-off relationship for six years
- The pair met after she emailed the band's official website
- She reported Watkins to police four years before he was arrested
- Ms Mjadzelics was in tears as she left court
- South Wales Police and CPS said they respect the verdicts
Ms Mjadzelics' solicitor Dale Harris said she had tried to force the "sleepwalking authorities to wake up".
He said: "It was like some Orwellian nightmare where the truth about Watkins became lies and the unsubstantiated rumour about Miss Mjadzelics became fact.
"Time and time again she reported Watkins and time and time again she was ignored.
"She decided to play Watkins at his own game and he eventually fell for it.
"And when he sent her child abuse images she sent went straight to the top."
He told reporters it had been his client who had tracked down the women who allowed Ian Watkins to abuse their children and who were later convicted along with him.
Des Mannion, head of the children's charity NSPCC in Wales, said after the verdict: "Figures obtained two years ago by the NSPCC showed that five UK police forces alone had seized 26 million images of children being sexually abused. Behind these abusive images are real children and these are not just images - they are crime scenes.
"The effects of this horrific treatment can last a lifetime for these children, many of those, if ever traced at all, will need specialist treatment to help them rebuild their lives.
"We understand what a difficult step reporting child abuse is, but we urge anyone with concerns to urgently come forward."
Ms Mjadzelics said it had been "her against the world", adding: "Me protecting the kids when everyone else called me liar, psycho - everything else - lie after lie.
"Let's just see how many kids could have been saved if the police had done their job.
"I've nothing to say to the police. This was a vicious prosecution."
The BBC's Sian Lloyd said Ms Majdzelics wiped away a tear as the jury delivered the not guilty verdicts.
The BBC's Mark Hutchings asked Joanne Mjadzelics if she felt could hold her head high now. She replied: "I could hold my head high yesterday so today makes no difference really."
Catrin Attwell, Senior Crown Prosecutor for the Crown Prosecution Service Wales' complex casework unit said: "The full circumstances surrounding this case have been aired in court. The jury considered the matter for a considerable period of time and found Joanne Mjadzelics not guilty of the possession and distribution of indecent images of children. We of course respect that decision."
She added: "Given the ongoing Independent Police Complaints Commission Investigation relating to complaints made by Ms Mjadzelics, it would be inappropriate to comment further at this time."
"Do I regret meeting him? Yes, I regret meeting him but if I hadn't met him then no-one would have reported him so I guess I can't regret anything because I was the one who kept going back and going back and reporting and reporting. Literally the whole world was against me," she told reporters.
"I couldn't keep putting my head in that place anymore, and they did nothing," Ms Mjadzelics said on the court steps.

South Wales Poilce Deputy Chief Constable, Matt Jukes, says the force remains committed to reviewing its investigation prior to the arrest of Lostprohets singer Ian Watkins. The matter has already been referred to the Independent Police Complaints Commission.
"We are committed to reviewing the case in this way and have already completed further reviews into supervision within public protection and our intelligence processes to improve our identification of risk."
The South Wales Police statement adds: "The safeguarding of vulnerable people and children remains our priority and it is right and proper for us to take evidence of this nature to the Crown Prosecution Service, who then make the final decision whether it should go before the courts."
Ms Mjadzelics was in tears as she spoke to reporters outside Cardiff Crown Court.

Ms Mjadzelics said after the verdict: "I shouldn't have even been here - just for doing the the police's job that they couldn't be arsed to do."
Deputy Chief Constable for South Wales Police, Matt Jukes, said in a statement "We respect the decision of the court today."
Ms Mjadzelics was first arrested in January 2013, a month after Ian Watkins and two women were arrested and remanded in custody on child sex abuse charges.
In December 2013, Watkinswas sentenced to 35 years for offences including the attempted rape of a baby. The women, both mothers of children he had abused, were jailed for 14 and 17 years.
Ms Mjadzelics was re-arrested in January 2014 and charged with four counts of possessing indecent images of children, two of distributing, and one of encouraging and assisting the distribution of an indecent image of a child.
Joanne Mjadzelics had argued all along her actions had been designed to trap Ian Watkins.
Ms Mjadzelics said in her trial that her only motive in exchanging images and explicit messages with Ian Watkins was to bring him to justice.
He was reported, by her and an unknown person, four times to the authorities in the four years before he was arrested.
An Independent Police Complaints Commissioninvestigation into the actions of eight officers from three police forces is ongoing to see if Watkins' celebrity status delayed him being brought to justice.
Joanne Mjadzelics is found not guilty of seven child sex abuse image charges.
