Toggle button to show and hide image

[lodi123]

Hi guys,



I'm looking for a macro for a toggle button (ShowHide) that will show an image in my document when I click on the button in the custom header and will disappear again when I click on it again.
The image is saved as a building block (Interim) and should be inserted in Table 1 Row 4 cell 2.

I can't get it to work on my own. Thanks a lot!!
