How to remove the blue border around an image

To remove the blue border around an image, follow these simple steps:

1. Left-click on the image
2. In the lower part of the editor, assign the value 0 to the parameter "Border width".

It is also advisable to insert a comment in the "Tooltip" box. This comment will be viewed by the recipient in case the image is blocked, or when stopping  the mouse pointer on the image  .

This text or comment is also useful for the disabled who do not have the chance to see the image. This way, the email message  will be more accessible.
