You can use image overrides to send different images for different marketplaces. This is useful if you already have images that are set for a specific channel and therefore either you want or need to send different images to other channels. This feature is available for all channels.
Here are the steps you need to follow:
1- Select the channel, find the product and you want to override and click the edit icon - shown below.
2- Click “Override” under the “Images'' tab.
3- You can either choose to override current images by clicking plus sign, or you can add new images to override the images with the new ones just only for channel level.

4- Save the changes.
You can always see the products which the image overrides by the labeling on it.
