    How to access and display the jpg file on the fly using js in clie

    I have a asp.net app, in the page there is a scan activex which could scan
    and save a jpg file in client harddisk.

    How could we access and display this jpg file on the fly using js in the
    client IE?

    Thanks,
    -Billy zhang

      Hi Billy,

      As for web page and javascript, it is not allowed to access client
      computer's file system. Actually, both IE7 and firefox restrict local image
      file viewing. So far based on my research, some workarounds availables are:

      1. Upload image to server-side so that we can use script to
      programmtically display an html <imgvia a server-side url

      2. Integrate the image displaying functionality into the ActiveX control.
      That means use ActiveX control to load local file image and display it.
      Maybe you can add another ActiveX control on the page to do the work.

      BTW, I found that silverlight 2 seems support local image loading.

      In Silverlight 1.1, it was impossible to load images from the local file system unless you uploaded them to a server first. In Silverlight 2.0, it’s a piece of cake […]

          Do you know any lightweight ATL control which could display jpg?

              Thanks for your reply billy,

              As for image activex control, I'm not sure about those commercial ones. If
              you want to build a simple one on the fly, you can refer to the following
              examples on code project which maybe helpful:
