Backgrounds can be used on pages and even on the front and back cover. pix2print has added a range of backgrounds, but also allows you to use your own photos or images as background.
Backgrounds can be dragged and dropped onto a page and if you want to use one background over 2 pages (a spread) you simply drag the background to the centre of the 2 pages. If you look closely you will see the blue line indicating where the background will go covering both pages.
If you want to use your own photo as a background, you can add the photo to the backgrounds (see How to add your own backgrounds) and then drag and drop the background onto the spread.
Alternatively you can drag the photo anywhere onto a page and then right-click on it and select: ‘Fit’ and then ‘Fit To Spread’. This is not tecnically a background, but by using the ‘Arrange’ options to ‘Send To Back’ or ‘Send Backwards’ you can then place photos on top of it, making it appear like a background.
Be aware that if you use the method where you add a background without saving it as a background in the backgrounds tab first and you want to add more photos onto that spread, that you need to add a picture box first and then drag and drop the photo into it. If you simply try to drag and drop a photo onto that page, it thinks you are trying to replace the background.
And remember you can use opacity to change the look of the backgrounds.
