The Image Manager interface, like all the Manager plugins (Image Manager Extended, File Manager, Media Manager etc.), consists of 2 sections, the Attributes section, and the File Browser section.
This section is divided into 3 parts, each accessible by clicking on the named tab. The default tab display is of the Image section, which contains the fields that represent the main image attributes of the currently selected article image, or the image to be inserted into the article.
Set the most common attributes for the image including URL, Description and Dimensions. See Inserting an image
Create rollover images. See Creating a Rollover image
Set advanced attributes for the image. See Advanced Options
The Image Manager File Browser has the same basic features as the other Manager plugins, with tools for creating new folders, uploading images and deleting, renaming, copying and moving files and folders. For more information on the File Browser features, see the File Browser section.
