A product image needs to be named using the conventions defined in the SuiteCommerce website setup record in order to be associated with the correct item in the webstore.
Whether you're adding new products, uploading new item images, or editing image naming reference fields (such as item names), clicking through hundreds of item records to check on associated images is a tedious, time-consuming, and now unnecessary task...
Anchor Group created a bundle that allows you to run saved searches on the item record to quickly find associated (or missing) product images. The bundle is a rapid, self-installation NetSuite bundle and has been released to the community for FREE*!
Here is a sample saved search that highlights items/products that are missing an associated image when the item is set to display to the webstore.
