Images
Valid URLs can be used to add images via your Google Sheet. We highly recommend hosting images locally on your website, a secure site or an FTP folder with 'Read' permissions.
To link to an image URL, enter =image("<add URL between quotations>") in the cell.
Caching
The 'Minutes to cache Google API calls' global setting determines how long it takes for documents and changes within the linked Google Drive folder(s) to be updated.
To edit the minutes to cache setting, open Developer Tools > Modules > Global Module Settings > Google API in your admin console.
