Honestly, my selection of Piczzle was just a very fortunate occurrence. I did a web search for companies that made puzzles from photos and there they were. Not sure what jumped out at me to select them, but I am glad I did. After reviewing their site, I had a few questions, so I emailed the company. I received a reply almost immediately. Following their suggestions, I created a collage of photos and saved them as a JPG (although they said they would have done this for me). I had yet another question about sizes and resolutions and again I emailed them. Again, almost immediately, they responded. Following their recommendations, I finished the JPG and submitted it through their website. Very simple. Within a few days, I received my completed puzzle, perfect. I am very satisfied with Piczzle! The puzzle was a retirement gift for a friend. The large puzzle piece sizes were perfect for her failing eyesight. The uniqueness of this gift was the hit of the retirement party and I’m sure it will be treasured by her for years to come.
