Hey guys and gals!

I'm planing a new mystery cache again! I want to make a series of "puzzle"-caches. I'm doing one where i hide 3-4 jigsaw puzzles in a box for people to take home and put them together. The coordinates for the final stage will be on the back :P I also wanted to make a virtual jigsaw puzzle for another cache in this series. But I have a problem, maybe someone of you guys can help me?

I need a free online jigsaw puzzle generator that alows me to use my custom pictures but gives me the option to NOT show the picture (or ghost of the picture) to the users (because then they would see the coordinates!). If someone knows a solution to my problem, please let me know!

So yeah, good luck on the giveaway and have a great day :-) Cheers!
