In order to use an image on your webpage you must upload them to the CMS first.
Uploading an image to Cascade CMS is done by using the red plus sign for adding content. This method ensures that the appropriate metadata is included with the image, making it search-engine friendly, and 508 compliant for visitors with disabilities.
The purpose of Alternative Text (Image Description) is to provide a description of the contents of an image file. One of the most common uses of Alternative Text is to provide text for visitors who can't see images in their browsers and are relying on screen readers.
Images uploaded to the CMS can be inserted into a page via a WYSIWYG editor by clicking on the Insert/edit Image button.
