How to Use the Chrome Extension for Reading Images
22 November 2023
Digimarc Validate can be used to identify digitally watermarked images on a web page.
The Validate tool doesn't ‘crawl’ entire sites. It's limited to the page you're viewing when you run the plug-in. The Validate Reader is a powerful solution enabling brands, rights holders, and digital-asset managers to better manage the use of images and other assets throughout the supply chain and across the internet. It empowers your in-house teams to run frictionless image-ID audits across any website to quickly scan for any images on the pages that contain your unique ID.
You can scan any web page. Try our test page to see how the extension works on watermarked images compared to unwatermarked images.
To get the plug-in:
- Sign in to My.Digimarc. If you don't have an account yet, see the Validate User Guide for instructions.
- In the Validate module, click Access Site to open the Validate web portal. Your ID and Account Status are displayed.
- In the upper-right corner of the page, click Downloads.
- From the Downloads page, click the link to download the Digimarc Validate Browser Reader. The Chrome Web Store opens to the Digimarc for Digital Images Reader page. Follow the prompts to complete the download. (Note: You must be signed into your user account with an active enterprise account to visit the downloads page.)
- Optional: After the extension is installed, open the Chrome Extensions menu and click the Pin to easily access the extension from your browser bar.
- Navigate to the website to be scanned for watermarked images and click the Digimarc Reader extension icon ( ) in your browser bar or extensions drop-down list. If you've signed out of your Digimarc account, you're prompted to sign in. The Validate Reader opens.
- Click Scan.
Validate displays all images it finds in the Reader window.
