'Declaration Public Overrides Property ImageDirectory As String
public override string ImageDirectory {get; set;}
WebHtmlEditor for .NET automatically assumes that all images are in the directory specified by WebHtmlEditor.ImageDirectory. For example (using WebHtmlEditor.BackgroundImageName as an example), if the value of WebHtmlEditor.ImageDirectory is "/ig_common/images/htmleditor/" (the default) and the WebHtmlEditor.BackgroundImageName property was set to "myimage.jpg", the control would assume the file can be found at "/ig_common/images/htmleditor/myimage.jpg". If the WebHtmlEditor.BackgroundImageName property was set to a string that has some form of directory designation, such as "slashes" within it (for example "C:\temp\myimage.jpg") the control would no longer assume that the image is within WebHtmlEditor.ImageDirectory but would use the full path you supplied for this property.
