Export to png bug

I used this widget to export a png of the tree I made for my page, but it picks the first node’s image and shows it in all the nodes in the image: Note: In the actual web page the nodes show the correct images. Is there any way to fix this? I have tried the export to pdf widget but it doesn't work as required either.

you need to use a unique top level class which covers all the elements in a single Div.
