The Node Appearance - Label / Image setting panel controls aspects of the label such as font color and size. This setting panel also lets you choose if the node label should display an image and how the label text should be aligned next to the image.
Node Type Selection
This dropdown shows which node type the rest of the settings below apply to.
Selecting a node in the graph or the tables while the setting dialog is visible will change this dropdown to show the selected node type.
In this case, the value of the attribute should be
a URL (http://www.google.com/intl/en_ALL/images/logo.gif)
a local path (c:\directory\image.jpg),
or a path relative to the file being opened. For example if the user is opening a data file named "c:\directory\data_file.xls" file, then an image attribute of "subdirectory\image.jpg" will be resolved as "c:\directory\subdirectory\image.jpg"
The other possible dropdown value is Node Tag Icon
This value may cause the Tag Icon to be displayed twice, once in the middle of the node body as an image, and once as a Node Tag in the upper right hand corner of the node. To hide the duplicate Node Tag choose the Show: None or Text radio button.
