How to use an app for iStock ESP

Some time ago, a new iStock ESP protection system made submitting through M+ and StockSubmitter impossible. However, we've developed a workaround in a form of a browser extension for Chrome. While the extension might also work in other browsers, please note that testing on is not yet complete.

How to Install

1. Download the ZIP archive and extract it to any folder on your computer
2. Open Chrome and go to Settings. Navigate to the Extensions section. Enable Developer mode at the top of the page
3. Click the Load unpacked button
4. Select the folder where you extracted the extension
5. Wait for the pop‑up notification to appear
6. Log into ESP. Keep the extension tab open until you've submitted all files!

After completing these steps, keywording, uploading, and submitting should work correctly. Upload speed depends on your internet connection. Your browser must remain open for the upload to proceed. For any questions, please contact M+ support chat.
