rkmarcks,
Thanks for the input. But I have a routine in the javascript that corrects for NT vs Unix and outputs the correct syntax file:///c| or file://.
This does work if I enter the "file:" directly as a URL in the browser, but does not work in the javascript, I still get the "illegal URL" error for Unix or NT.
What I am attempting to do (and this works in older browser versions) is to let the end user display an image from thier local machine in a frame to compare to a stored image in another frame.
This is for an itranet application.
Would appreiate any help.
