In order to make an image show up without their custom treatment (the border, padding, etc), you will need to add custom styling to the image via the Advanced Settings.
- Click on the Image and click EDIT IMAGE
- Click the ADVANCED SETTINGS tab
- In the Advanced Image Settings–>Styles box, put this code:
margin: 0px; -moz-border-radius: 0px; border-radius: 0px; border: 0px; padding: 0px;
- Update. Done.
