Image Properties
You can set or modify properties of an image using the image dialog. It allows you to add links to images, apply border and additional styles. The editor provides option to specify the alternate text for an image, if the image cannot be displayed.
Resize an Image
You can able to resize an image either manually or set the width and height in the image dialog.
Resize Manually
You can resize an image by manually select an image, and drag a handle until the image is the desired size.
NOTE
Set the default height and width of the Images which was inserted into the RTE text area in “change” event of RTE – <p>Link</p>
Set Width and Height
The editor provides you to set the width and height properties to change the size of an image (rather than forcing you to set in style attributes) using showDimensions property. By default, the Constrain Proportion checkbox is selected to resize an image to an exact proportion. To apply the exact width and height that you specify into the Height and Width textboxes, uncheck the Constrain Proportions checkbox.
