(Note: The change caused by this menu option is only 
visible by opening another hypertext file or by using 
a jump link to another file.)

The "Show Images in Dialog" menu option sets a flag
which is used by the OnAssertShow....Image  
method of the HTDisplayBox component. This method 
is used to override display of images. In this
case, if the flag is true, images are placed in
a dialog box before being displayed in the main
form. (This could be used to abort displaying of
images for security reasons.)

(Note: Assert methods normally are used to abort
all further processing of an action, while the
Handle Methods modify the processing. These
two methods can each be overridden in code by
direct assignment for Assert types and virtual
overriding for Handle types.)
