It is not uncommon to be missing portrait photos for multiple students. When this happens you can handle it different ways on the portrait pages.
We recommend that you do not use a blank space or a placeholder for a missing photo but rather a text box that lists the names of the students not pictured. This will keep the page uniform while still acknowledging the students who do not have a photo available.
Adding a placeholder where the student's photo should be is another option. Before deciding on this option, take a look at the page examples below.
Here is a side by side view of the same class. On the left page, blank spaces have been created where students' photos are missing. You would need to add a text box for each blank space to add the student's name. On the right page, there are no blank spaces but a text box added after the portraits to list the students who do not have a photo available.
If you decide that you prefer a placeholder we recommend using one that is colorful and fun, such as your school's mascot. Compare the pages below and see how the different options look.
Adding a placeholder image would be just the same as adding a missing students image. You can find instructions on how to do that here: Adding New Photos to Portait Autoflow Sections
