# Constraints

There are a few things to watch out for when creating your book.

  • A red X in the photo - This indicates a photo with a DPI (dots per inch) of less than 200, which is a subjective minimum for photo quality printing. This is just a warning and will not display in the book. Things to try include:
    • reducing the size of the photo (thereby increasing the DPI),
    • replacing the photo,
    • shuffle the page layout, or
    • removing the photo.

At this time it's not possible to add or replace photos in TrackMyTour Books. If you need to add or replace a photo then do it on your map (using the app or website) and start a new TrackMyTour Books project.

  • Text with a red background - This indicates a caption or title extends beyond the bounds of the space allocated to it. Things to try include:
    • increasing the size of the allocated space,
    • moving the text to its own page,
    • shuffling the page layout,
    • reducing the font size,
    • editing (by double clicking) and reducing the text content, or
    • removing the text completely.
