asp classic - Upload and display picture -

-

i have created shadowupload.asp , upload.asp. works but, want display picture uploaded don't know how display it

my source code is

<!-- #include file="shadowupload.asp" --> <form action="<%=request.servervariables( "script_name" )%>?action=1" enctype="multipart/form-data" method="post"> picture profile: <input type="file" name="file1" value="<%=mypicture%>" /><br /> <button type="submit">upload</button> </form>   <img border="0" src="<%=mypicture%>" width="90" height="100">`  <% dim objupload if request("action")="1" set objupload=new shadowupload if objupload.geterror<>""  response.write("sorry, not upload: "&objupload.geterror) else  `          response.write("found "&objupload.filecount&" files...<br />")         x=0 objupload.filecount-1`              if (objupload.file(x).imagewidth>200) or (objupload.file(x).imageheight>200)                 response.write("image big, not saving!")             else                   call objupload.file(x).savetodisk(server.mappath("uploads"), "")                 response.write("file saved successfully!")             end if             response.write("<hr />")         next      end if end if   %>

you need add image every file uploaded, , if uploaded successfully:

if (objupload.file(x).imagewidth>200) or (objupload.file(x).imageheight>200)     response.write("image big, not saving!") else       call objupload.file(x).savetodisk(server.mappath("uploads"), "")     response.write("file saved successfully!")     response.write("<br /><img src=""uploads/" & objupload.file(x).filename & """ height=""50"" />") end if

this show preview of uploaded picture, set height of 50 pixels.
