that's my code :

 <script type="text/javascript">
  $(document).ready(function(){
   $("#<%=fileUpload.ClientID%>").change(function () {
    alert(// width + height ); 
    });
    });
   </script>

<asp:FileUpload ID="fileUpload" runat="server" class="upload"   />

Can i get the width and height of uploaded image from client side ??

How would you get the attributes of the image before the image is uploaded ? How could you be sure its even an image ? The client or server does not know anything about the file prior to upload. As far as I know, you can only get the name and size of the file.

  • that's just a peace of my code i can detect the type of the uploaded image but how can i check for it's width and height ? Commented Sep 4, 2012 at 11:08
  • Like I said, before the image is uploaded, you can't get anything else than file size and name. By "detecting" do you mean using a filter for the file selection dialog ? That is far from a bulletproof detection method. Commented Sep 4, 2012 at 11:13
  • check this link jsfiddle.net/4N6D9/1 it's not working for me maybe because i'm using an asp control but i want a different solution Commented Sep 4, 2012 at 11:15
  • For the third time: the file needs to be uploaded for this to work Commented Sep 4, 2012 at 11:18

    No. No. No. No. No. No. No. A completely different thing is if you load an existing image from the web, but getting anything else than file name and size of an image that resides in a user's drive, no. In your code, you just create an empty image and try to load if from a URL. Commented Sep 4, 2012 at 11:25
