Image Pre-View in form.

I have a image upload PHP script. It uploads via HTML form. Im wondering how i could make the form so when you hit browse, and select the image it appears in a box on the page, sort of as a image preview, before the form is submitted. I have everything working great, im just wondering how i would implement this into the form. Any healp would be greatly appreciated.


Thanks,
Ryan

As far as im aware this is not possible, you cannot access files on the users computer until they have been uploaded. If you really want a preview before you upload the image then i think it could be done by either using ActiveX or Java Applets, both with their own issues and problems though.
