Michaela Sheldrake was told by a judge that she had shown no remorse over her offending.
A barrister who represented the 41-year-old in court said Sheldrake had described herself as a “monster”.
Sheldrake, of Noster Hill, Beeston, was sentenced today after admitting nine offences at an earlier hearing.
They included two charges of taking a total of 356 indecent photographs of a girl aged under 16
Three of the photographs were classed as category B and 353 were category C.
Sheldrake also admitted two charges of making indecent photographs of a young boy in connection with two images classified in category A - the most serious category - and five in category B.
Sheldrake admitted one charge of inciting a girl aged under 16 to engage in sexual activity and one charge of engaging in sexual activity in the presence of a girl under 16.
Sheldrake admitted possessing 2,578 indecent images and 110 movies of children on a mobile phone.
She also admitted distributing indecent photographs of a child and attempting to pervert the course of justice by encouraging a child to provide false information to police.
Catherine Silverton, mitigating, said Sheldrake had no previous convictions and was ashamed of her offending.
She said: “Nobody hates her as much as herself.
“She described herself as a monster.”
Miss Silverton said the case has been going on for almost three years.
Jailing Sheldrake, judge Sally Cahill, QC, said: “It is said on your behalf that you have shown remorse.
“I have to say that, having read reports and reviewed the evidence, there is no real evidence of that in relation to your victims.
“You have realised the consequences of your behaviour and the consequences are severe.
“In my view you have not shown any real remorse,”
