If you need to make some quick simple edits to your product image, you can use the built-in simple editor right from the Product Edit page in Dropified.
Just hover over the product image that you want to edit, then click the Simple Editor icon.
From the popup image editor, use the simple tools to edit your image, then click Save.
Make sure to click the green button at the bottom when you're done so that the changes can be saved.
Note: if you need to edit product images within Dropified, then you need to go to the Addon store section of your account to have In-App Photo Editor tool added to your account.
You can watch this video demo to show you how it works:
