News of The Sun's reward follows the Royal Queen's Lancashire Regiment calling on the Daily Mirror to issue an apology.
"The Sun newspaper announces today that it is offering a £50,000 reward for information which results in the arrest and conviction of those responsible for the faked pictures published in the Daily Mirror which wrongly claimed to show the mistreatment of Iraqi detainees by British forces," the newspaper said.
Yesterday, the government said yesterday that the pictures, published by the Daily Mirror, were "categorically not taken in Iraq".
Furthermore, the Armed Forces minister Adam Ingram said that those who took the pictures, thought to have been taken at a TA base in Preston, could have committed "criminal offences under military law".
In a statement issued today, The Sun said anyone with information on the pictures should contact it in confidence.
The paper said that it would pass the information on to the Royal Military Police, the Special Investigation Branch of which is carrying out an inquiry.
"The Sun believes that someone, somewhere knows who was behind this despicable action, which has falsely brought shame on a great regiment, wrongly besmirched the reputation of British troops in general, and exposed our forces in Iraq to terrible peril.
"If someone knows who faked the pictures, we say this: Call us in total confidence. We will pass on your information to the Royal Military Police who are conducting the inquiry."
