Hello,
I would like to know how could I insert a picture showing the parameters concerning my own macro
For exemple, if the macro draws a box, the user has to enter 3 parameters

When I execute the macro, it opens correctly, but there is no picture

For exemple, if you want to create an InfiniteBox, there is a picture showing you de dimensions you have to enter

You can even make the picture visible or invisible with the "Image" (in french version) button.
Does anyone know how to do this?
Regards!
Andres
