While placing an image into a single frame in Adobe InDesign is simple, placing that same image and having it span multiple frames isn’t quite as obvious. But it can be done, and it’s actually quite easy.
The first thing to do is to create your image frames using a Polygon tool or creating a custom shaped frame with the Pen tool. The next step is to select each of the frames you wish to combine with the Selection tool (solid arrow).
With all your frames selected, visit Objects>Paths>Make Compound Path (or simply hit Command + 8). As you can see in the image above, when you convert multiple frames into a single Compound Frame, it essentially becomes a single frame again – even though you can still manipulate each frame independently. Now simply place an image in the Compound Frame and size it accordingly.
