If LogErrors is false all errors will be logged only to the
standard error output. If your code does not handle errors properly
then errors may get missed in production output. By setting this
property to true all errors will also be directed to the
Application event log as Warnings which can be periodically checked
to ensure the integrity of your web site.
This value is 'sticky' so that if you change it to a particular
value it will always stay at that value. This property is shared
between all the instances of ImageGlue on your computer.
