Insert images into Google Sheets when offline
We’re making it easier for your employees to work on the go—and without Internet access—in Google Sheets on the web. With this launch, people can now insert images into Sheets even when they’re not online, provided they’re working in Chrome and have turned on offline access. Those images will be synced once the person gets back online. Try it out in Google Sheets today.
