Just like many other elements, images can be given borders and rounded corners, they can
have inner and outer margins and they can be rotated. How to do this is described in general
formatting topics, such as "Border" on page817 and "Spacing" on page829. All general
formatting topics are listed under "Styling and formatting" on page785.
Note
It is recommended to resize images outside of the Designer, with image editing software.
If necessary, it is possible to resize images automatically via a script in a Workflow
process, as explained in a how-to: How to resize images via a script.
Setting an alternate text
Once an image has been inserted in the content of a template, it can have an alternate text.
The alternate text will be shown in emails and on web pages at the position of the image while
the image is loading and when the image is not found. On web pages, alternate texts are also
used for accessibility.
To set an alternative text, click the image and enter the alternate text in the Alternate text field
on the Attributes pane at the top right.
Using a CSS gradient to create an image
CSS gradients are a new type of image added in the CSS3 Image Module. CSS gradients let
you display smooth transitions between two or more specified colors, while repeating gradients
let you display patterns. This way, using image files for these effects can be avoided, thereby
reducing download time and bandwidth usage. In addition, objects with gradients look better
when zoomed in a browser, and you can adjust your layout with much more flexibility.
For more information about the various types of CSS gradients and how to use them, see
