If you would like to change the image that appears with your article when displaying as part of your email, website, or other channels, you'll want to click the edit button on the content card after it has been placed in one of your collections (need to find where that is? Click here.)
Once you click that button, you will be able to edit the article's summary as well as the image.
Another way you can change the image of an article is when you add an article to your Collections from Topics. In the "Add to Collection" pop-up, you will be able to change the image for your article here as well.
You are able to select an image from your own files on your system, or if you have purchased a license to Shutterstock through UpContent's "Image Booster", you can choose an image from there as well.
The image that you decide will fit best with your curated article will be the image that your audience views with the third party article whether it be on your own website, your email campaign, or even the content you are posting to your social media accounts. This, of course, will not change the image presented on the publisher's site.
