Images from .iba in Pages

When I open a .iba file in Pages, the images are all gone. Instead there is a placeholder and the message "Interactive Image widgets are not supported in Pages. Widget content was saved as a separate file: PageN_InteractiveImage.pages (N signifying the corresponding number of the image). Where are these files located on my MacBook? I tried doing a search by file name and was only referred to the internet.

Thx.
