Here is one pdf file which is an example of which can be a model for this assignment, and here is second. Both include images and text and are connected in theme. The images and information about them come from the AMICO Library site which can be reached from LIAS E-Resource.
To make pdf multipage file using InDesign, begin by opening the program and creating a new document. Notice that the landscape orientation is chosen - that orientation works well on the screen, for print the portrait orientation is more often used.

This will give a ten page blank document through with you can easily navigate using this box:

Save the InDesign file in the same folder or directory where the images to be used are stored. The images should be saved at a size which will fit the page - no more than 9" wide or 7" tall - and between 100 and 300ppi.
Starting with the first page, a text block is entered image placed:


Text is entered in the text block, carefully choosing the face and size (in this case, Big Caslon).

Those steps are repeated on page 2 and the following pages:

The project is finished by both saving the file as an InDesign file (so it can be easily edited and added to) and exporting it as a PDF file:
