Four 'selfies' have played a crucial role in the downfall of drug dealers locked up for a combined total of almost 63 years.
George Marsh, Carl Stewart, Gary Mitchell and Nathan Harding were busted after detectives linked them to damning messages shared via EncroChat.
Each of the men were identified when photos of their hands were retrieved from their accounts and analysed for fingerprints.

Dozens of men from Merseyside have been jailed after being linked to texts and photos shared via the EncroChat communications platform.
Investigators breached the network in an international operation last year, with the authorities claiming the service was used by criminals to plot their exploits.
With users working under codenames, known as handles, linking the accounts to the people behind them is a significant challenge for police.
But in some cases that process has been made easier by pictures sent through the network.
Harding used the handle MagicCider to sell heroin, cocaine and cannabis worth around £1.5m.
The 30-year-old, of Maud Street in Toxteth, was brought down after detectives found his fingerprints through analysis of a photograph he sent of himself holding cannabis.
He was jailed for 18 years and five months.
Marsh went by the codenames SneakyStem and WackySilver but his secret was unearthed partly as a result of a similar image.
The 33-year-old, of Park Road North in Birkenhead, was linked to the distribution of 25kgs of cocaine, 110kgs of cannabis and 1kg of ketamine and pleaded guilty to conspiracy to supply each of the drugs.
He was sentenced to 16 years.
Mitchell was sentenced to 15 years after he admitted conspiracy to supply heroin, cocaine, ecstasy and cannabis.
The 43-year-old, of Mosslands Drive, was linked to plots to supply 27kgs of heroin, 17kgs of cocaine, 159kgs of cannabis and 7,000 ecstasy tablets across Merseyside.
His picture of his own hand holding a sample of cannabis played a crucial role in detectives' efforts to link him to the StarkIsland account.
Perhaps the most bizarre image to snare an EncroChat criminal was the one linked to Carl Stewart, however.
Stewart, 39, and of Gem Street, Vauxhall, was jailed for 13 years and six months after he pleaded guilty to conspiracy to supply cocaine, conspiracy to supply heroin, conspiracy to supply MDMA, conspiracy to supply ketamine and transferring criminal property.
He was pictured not holding drugs - but a block of Stilton cheese.
