@Pommette, while the macOS won't do this for you, KM will.
Click on the Macro name in the "Macros" panel, then Goto menu Edit > Copy as > Copy as Image. It will copy the entire macro image, even if itis not visible.
Note that this copies ONLY the image, and NOT the Macro file, like the Share button that Chris mentioned.
You can also use this macro to automate upload of both image and file:
Macro: [KM] UPLOAD Macro to New or Existing Topic
