Editing images in Writer

Hello, I’m looking for a way to edit 4 pasted pictures (maybe their layers or something) to make composition like in this. The additional point is that each of elements must move independently from others.

I think, that it is not possible, because the stacking order applies to the whole object. You will need to fake it, e.g. cut one picture into two parts, or insert the picture twice and crop the not needed part.
