The number of children in need of foster care has risen for five years in a row, a charity has said.
The Fostering Network Scotland said that a child enters the care system and needs a foster family every six hours in Scotland.
The charity added that 1000 extra carers would be needed in 2012 alone and has issued an appeal for people to become fosterers ahead of Foster Care Fortnight, which starts on Monday May 14.
On any one day there are more than 5000 children living with 3300 foster families across Scotland. Across the UK, the number of children who need foster parents has increased by 17% since 2008.
Sara Lurie, director of the Fostering Network Scotland, said: "More than 24,000 children who came into care last year were fostered. That means a foster home has to be found every 22 minutes.
"There is an overwhelming need for more people to come forward to foster across Scotland. With more foster families, children in care will have a better chance of finding the stability and security they need to go on and achieve their potential."
Stewart Duncan, from Edinburgh, has been a foster carer for 15 years.
He said: "It's really rewarding when you see the day-by-day improvement in a child.
"You see them build up self-esteem and come out of their shell. Then you know you are really making a difference, you see their confidence grow and they start to make friends."
