AdoramaPix photo books are printed at 300dpi (dots per inch). Chances are the monitor you are using to view your photo book is displaying a much lower resolution. As a result, it is possible that two objects on your page will look like they are touching when you preview them on your screen but have a visible gap between them when you receive the printed book. There are a few things you can do to minimize this issue. Shown below is an example of a page with three photos placed one pixel apart.

Option #1 - Zoom in. Use the slider below the workspace to get a closer look at your page. When you zoom in closer, small gaps become more visible. This increases the likelihood you will spot a misalignment. If you're not certain about the placement of your photos, its a good idea to zoom in to the maximum size and look closely at your page.

Option #2 - Change the background color to one that doesn't contrast heavily with your photos. Notice how the seams almost disappear in the image below when the background is changed to green.

Option #3 - Choose a high contrast background in order to spot gaps more easily. The chances you won't spot a gap are increased if the background color blends somewhat with your photos. If you deliberately set your background to a color that is very different from that of your photos, the gaps will be easier to see. Below we changed the background to red. Your best choice for a contrasting color is to choose a complementary color to the most common color in your photos.

Option #4 - If you want to be absolutely positively sure, then check numbers. The object properties window will let you enter precise coordinates for any object on your page and see the precise position.
