Not really sure what happened to your layouts--esp since you did a test run. But I would recommend going with a better printing service in the future. Like Mpix or Smugmug. There are others that are high quality as well. I use Smugmug (which actually uses EZprints to do there printing--smugmug is the photohost site) and when you order prints, it shows you what you are going to get. You can choose cropped or uncropped. For cropped prints, there is a box around the portion of the pic that will show up if it is not the correct ratio of length and width (and you can adjust what part of the pic has the box around it). If you choose uncropped, then the pic will be fit onto the size sheet you desire with white around the remaining part of the sheet.

I think that Mpix supposedly gives slightly better quality prints but I really like the user interface and layout on Smugmug. I haven't ordered any prints from Mpix.

So sorry that your layouts got messed up. That is very frustrating
