A pioneering project is under way to trace child abuse victims whose pictures appear on the internet.
GMP seized nearly 1m indecent images of children in a year
Greater Manchester Police has joined forces with the NSPCC in E-Spy, which also targets paedophiles.
The charity has worked with police before on cases, but this places them full-time with investigators.
NSPCC director Wes Cuell said he hoped the initiative would bring abusers to justice, saying: "Behind the images are real children who have suffered."
In the last year, Greater Manchester Police (GMP) has seized more than one million indecent images of children, many of which appeared on the internet.
Assistant Chief Constable Dave Whatton, of GMP, said: "Project E-spy aims to show that victims and their abuse can be traced given the resources.
"The making and trading of child abuse images recognises no geographical boundaries.
"GMP has linked up with NSPCC, which works across England, Wales and Northern Ireland, to ensure images are tracked and intelligence shared no matter where the abuse originates."
The force has one of the largest abusive images units in the UK.
Mr Cuell, the charity's director of services for children and young people, said: "The internet has made it much easier for paedophiles to organise and exchange images that fuel the horrific market in child abuse.
"We must make sure that children are protected and families supported."
