The parents of missing Madeleine McCann have said they will "travel wherever is necessary" in their search to find their four-year-old daughter.
The McCanns told reporters they would search far and wide
Gerry McCann said he and wife Kate would play a key part in trying to find her, including travelling around Europe to raise recognition of her plight.
Mr McCann said that since Madeleine may no longer be in Portugal the search for her would extend "far and wide".
Madeleine from Rothley, Leicestershire, disappeared in the Algarve on 3 May.
Mr McCann, who has returned to the resort of Praia de Luz after making a brief trip to the UK, said the family was "nowhere near ready" to leave Portugal.
He said he had met organisers behind a fund to help find his daughter.
"Kate and I will play a key part in that campaign. We will travel wherever is necessary to ensure people across Europe recognise Madeleine's picture and we will encourage them to come forward with any information which might lead to Madeleine's safe return."
Some of the money collected by the fund will be used to appoint a campaign manager. Hiring private investigators was not on the agenda at the moment, said Mr McCann.
Mr McCann arrived back in Praia Da Luz on Tuesday morning after his one-day visit home.
During his trip, Mr McCann visited the family's home village of Rothley, where he saw the thousands of yellow ribbons, tributes, flowers and cuddly toys left by the public.
Mr McCann said: "It was extremely difficult to leave here without Kate and when I went to Rothley I knew we should have been coming home as a family of five, there's no doubt about that."
Standing by his side, Mrs McCann said: "It was quite moving for me to see Gerry in Rothley again. It has just emphasised to us how much support we have got there and everywhere really, and that really helps."
On Wednesday, the couple, who say they have drawn strength and support from their faith, plan to visit the Roman Catholic shrine in Fatima, in central Portugal, to pray for Madeleine.
Speaking to reporters on Tuesday afternoon, Mr McCann said he was particularly encouraged by the UK police appeal for photos and information.
He felt confident that the latest appeal would lead to information that led to Madeleine's safe return.
The police said they wanted pictures that included strangers in the background, but not family or empty scenic shots.
Photos can be uploaded via a website - www.madeleine.ceopupload.com.
The photographs will be cross-referenced against a database of pictures of UK paedophiles and other criminals, with police able to check 1,000 an hour.
UK POLICE APPEAL
Photos with strangers in the background
Taken between 19 April and 3 May
Volunteer searchers to contact police on 0800 0961233
Any relevant information will then be passed on to the Portuguese police.
Mr McCann also repeated the UK police appeal for anyone who took a part in the initial search for her, before the Portuguese police arrived, to contact police on 0800 0961233.
As well as uploading them, police say the public can take any photos they might think relevant to high street photography shop Jessops, which will convert traditional prints to digital images for free.
Mr McCann declined to comment on the Portuguese police's only formal suspect in the case, 33-year-old Robert Murat, a British man who lives close to the McCanns' hotel.
Portuguese police have also confirmed they are investigating claims of a possible sighting of Madeleine in Morocco.
Chief inspector Olegario Sousa said the clue was "being verified" and that the Moroccan authorities had been contacted.
