Hi all,
I have installed ZukerReport in my Sugarcrm.Now while reading ZukerReport manual there told that

Post-Installation Steps
Picture Files

Copy the files starting with “Zucker” from the directory
<Sugar>/themes/Default/images into the images subdirectory of the theme you are
using (<Sugar>/themes/<your-theme>/images).

but here as told there are no files in /themes/default/images related with ZukerReports.
i found these files in /custom/themes/default/images.

i am putting this here because it may help anybody going through same.
