I'll paraphrase the 1st paragraph in the 2nd column, on page 192.
"Choose the button 2nd down from the top on the right hand side of the workspace to 'create a new picture frame and insert a picture'. It will open in a sub-folder called 'English' within a folder called 'Contents'.
When you select a picture folder say 'Architecture' an 'Insert CD-ROM disk' screen will come up to insert a separate content CD - click CANCEL as the photos have already been placed on the PC Advisor CD for you.
Navigate to a separate sub-folder called 'Photos' which is still within the folder called 'Contents'. Continue to click on the sub-sub-folders within 'Photos' to find the 150 pics.
