Hi again,

Can you please provide a sample with your issue so I can investigate further and hopefully provide you with a satisfying solution!

Thanks,

Actuly there are multiple section node

then each section has mulitple category node

and each category has multiple item node.

and each category has there own image.

i have 12 section node so i have 12 diffrent images,

only few section Category  nodes images are diffrent otherwise all are some.

if i will count total different images.then i am using total 15 different types of images for nodes.
