Yes this is possible, but …
the real question is: What should happen with these elements after placing them?
What you have to do:
Look at this example file: http://image-grid-2.businesscatalyst.com/index.html
You may download the corresponding .muse file directly from the site – if you find the trigger! Just hover over the elements and look, how they behave!
You may also have a look at this site. http://image-grid.businesscatalyst.com. It is a little bit more complicated, but works the same way.
If you don’t want to create something like this by yourself (I’d suggest to do it, because it is a really, really great way to learn, how Muse behaves!), you can choose from many 3rd party widgets out there! This is a great starting point: https://musewidgets.com/collections/all/image
