A directory where images can be found.
When this property is set, any image specified for an UltraWebToolbar item, will be relative to this directory.
To specify an image in the current application directory, use a ./ prefix for the image name as in: ./myimage.gif
Developers must always use forward slashes ('/') in the path specification of this property. Use of the virgule ('\') in this property may cause a broken image link when the end user interacts with some UltraWebToolbar items.
