(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 as Filenames" menu option sets a 
flag which is used by the OnHandle....Image  
method of the THyperTextParser component. 
This method is used to modify processing of 
images detected by the parser. In this case, it
replaces any image sent to it with text containing
the image filename. (This could be used to
allow quicker display of inline images.)

(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.)
