Dear Team,

Where can i find the settings to enable Second Picture on Products, so that any product when mouse hover shows the second Image. I have checked the code , but i could not find the settings to enable the secondary images on products. Kindly help

It's hidden setting not available in standard settings menu. You can search for it directly from All settings (advanced). Search for catalogsettings.secondpictureoncatalogpages and set its value on True.
