Change the box header

Hello,
I'm in the process of tweaking the default template.
I want each box (Shopping Cart, Brands, Categories, Bestsellers,...) to have its OWN image at the top.
The final result I want to achieve is that the boxes in the sidebars are different from each other.

Can anyone help me on how to do this please?

.

Just edit the module files you're wanting to update in the folder

/catalog/view/theme/[your theme name]/template/module/


Good luck
