The parents of missing British girl Madeleine McCann say they will leave "no stone unturned" to find her.
The McCanns said they remain positive and focused
Gerry McCann said he and his wife Kate remained "positive and focused", while the police investigation continues.
Three-year-old Madeleine, of Rothley, Leics, disappeared from a resort in Praia da Luz, Portugal, on 3 May.
A message from the McCanns thanking people for their support has been read out at a service at St Andrew's Roman Catholic Cathedral in Glasgow.
Madeleine's uncle, John McCann, said the family were grateful for the "outpouring of solidarity".
"Please continue to drive support around Europe, get people to access information," their message said.
"We remain confident that Madeleine will be found soon and your prayers and efforts will bring this about."
Mr McCann comes from Glasgow.
A Scottish tycoon has offered a £1m reward for information leading to Madeleine's return and Real Madrid star David Beckham has made a televised appeal in Spain urging her safe return.
There has been speculation Madeleine could have been taken over the border.
BBC correspondent Richard Bilton said Spanish police had been briefed on the case by their Portuguese counterparts.
But he found no appeal posters in the Spanish town of Ayamonte, less than an hour's drive away from where Madeleine was taken.
Real Madrid player Beckham, who held up an poster written in Spanish, was the latest in a line of footballers to appeal for information.
Neil Lennon, captain of Scottish champions Celtic, also made a television appeal on Friday.
Cardiologist Mr McCann earlier said he and his wife, a GP, had seen at first hand how strong the police's desire was to find Madeleine.
He said: "We are doing absolutely everything to assist the police with their investigation and we will leave no stone unturned in the search for our daughter Madeleine.
"We are very grateful for all the efforts and offers of support that we have had from home and around the world.
"We have been moved by the enormous willingness of people to do all they can to help find Madeleine."
The £1m reward has been put up by Stephen Winyard, 57, who owns Stobo Castle in the Scottish Borders.
The official ground search for Madeleine in the Algarve has ended, but police say they still have significant leads to follow up.
The focus is shifting from being a local search for Madeleine to an international child abduction inquiry.
On Thursday Portuguese police said ground searches, which have covered nearly 80 square miles, were being scaled back as the results had been "zero".
Police with dogs searched the McCann's holiday apartment again on Thursday evening.
Media reports about leads have focused on CCTV footage from a petrol station on the night of Madeleine's disappearance.
It was thought to feature two men and a woman driving a car with a British number plate.
Police have declined to confirm or deny reports about any possible leads, citing Portuguese law.
British child abduction experts have also flown to Portugal to assist the investigation.
The UK's Child Exploitation and Online Protection Centre (CEOP), which works to tackle child sex abuse, has launched a poster campaign appealing for information on Madeleine's disappearance.
The international number for Crimestoppers is +44 1883 731 336. People with information about Madeleine can call anonymously.
