Duinrell question

[sycamorescrumptious]

Hoping someone can help here please - we're heading to duinrell in a few weeks and know we need to take passport style photos with us, I'm wondering if these need to be the proper ones on photo paper or if we would get away with appropriately sized ones on normal printer paper - does anyone know please?
Don't fancy spending >£20 for unnecessary passport photos!

Printed are fine! You just glue them to a pass - we used self-taken passport photos

Any passport sized photos on any paper are fine. Although you can print proper photo paper ones for about 40p in Boots which are probably more durable.

Amazing, thanks both!

As others have said, any photo is fine (I cut faces out of larger photos, one of which had a giraffe in the background). Have an amazing time, we went last year and loved it. Make sure you try Luciano's ice cream in Wassenaar (easily walkable from the site).
