And where do you intend to store the images: on the filesystem or in a database?

Just use an upload control and then save it to the server and create an img with the src set to the image. What have you done so far?

Hi,

You can use FileUpload control to upload your file and then you can Save that file in the server. (See this[^])

If you want to store your file in database then you can store it in varbinary field.(See this[^])

Hope this is what you want to know.

XML

<div>
       picture
       <asp:FileUpload ID="Fud_Pic" runat="server" onchange="PreviewImg(this)" />
       &nbsp;

     <br />
   <br />
   <br />
    <asp:Label ID="Label2" runat="server"></asp:Label>
   </div>



   <div id="newPreview">
       </div>

<asp button......="">

.cs_page
under the button click write this

XML

if (Fud_Pic.HasFile)
       {

           Label1.Text = "filelength:" + Fud_Pic.FileBytes.Length
               + "<br />"
               + "filename:"
               + Fud_Pic.FileName
               + "<br />"
               + "mimetype:"
               + Fud_Pic.PostedFile.ContentType;

           Fud_Pic.SaveAs(MapPath("~/images/")
               + Fud_Pic.FileName);

       }

       else
       {
           Label1.Text = "no files";
       }

it works fine...........

if u need a popupimage use this javascript

XML

<head runat="server">
    <title>Untitled Page</title>
    <style type="text/css">
        #newPreview
        {
            filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(sizingMethod=scale);
        }
    </style>


    <script language="javascript" type="text/javascript">
    function PreviewImg(imgFile)
    {
        var newPreview = document.getElementById("newPreview");
        newPreview.filters.item("DXImageTransform.Microsoft.AlphaImageLoader").src = imgFile.value;
        newPreview.style.width = "80px";
        newPreview.style.height = "60px";
    }
    </script>


</head>
