Swapping Symbol Image

[mark-paper]

Hi you all,

I need some help with the display of an image (symbolButton) in a UI (window and formLayout) I have created.
Basically it has to change according to the value (1/0) that an attribute get along the time line.
In few word the swapping has to be dynamic along the timeline.

Any one of you, masters, has an idea about how I cpould takle this issue?

Thanks in advance for your kind help.

Cheers
Mark
