software to make this

[GJ02]

Hi guys

Im after some help please
just after my son was born I created this photo / collage using a free online service.
It allowed me to upload the image, choose how many a4 pages would make up the whole picture, it would then create the photo in a pdf format and i would print each individual page off to create the whole picture.
But I cant for the life of me remember the name of the website.
So, im either after the name of the site or another free software or service that will allow me to do this

6 x A4 =
