Hi,I've upgraded to latest version of Stimul(2019.3.4) but now just before a custom toolbar button is inserted a image,image is gone if I return to my previous version (2019.3.2):



button is added with this code:
viewtopic.php?f=27&t=55190&p=152642#p144859

Hello,

You should send additional parameter null
var userButton = viewer.jsObject.SmallButton("userButton", "My Button", null);

Thank you.
