    Iam trying to build a simple image gallery,that displays image form the files on web server and displays it on webpage.

    I tried, but my code displays some random text instead of an image. Here is the code:

    <%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>

<body>
<% dim objFSO,objFolder,objFile,objOpen
Set objFSO=Server.CreateObject("Scripting.FileSystemObject")
Set objFolder=objFSO.GetFolder(Server.MapPath("hall"))
for Each objFile in objFolder.Files
Set objOpen=objFile.OpenAsTextStream(1)
 do while Not objOpen.AtEndOfStream
  Response.Write objOpen.ReadAll
 Loop  
 objOpen.Close
 Response.Write "<br>"
Next
Set objOpen=nothing
Set objFolder=nothing
Set objFSO=nothing
%>
</body>
</html>
    Code (markup):
    What is happening? How can I display the image from a file?
    Plz help..

    perhaps there are too many files in that folder
    or many files are not image files and those files keep running.

I don't see the sixth file..not even when I opted to view the hidden files. I don't knw from where it came. But yes when I was trying to find out the sixth file I saw somewhere its a DB file..but how to access that file? And I never put a DB file..so from where did it came? nyways..now the question is how to acces that file and delete it from there?

    Yes, you can deleted it.

    Can you ASP.Net instead? I have a script I use to do this written in .Net in about 3 lines.

    If you are a noob, why are you trying to learn an (almost) dead language?

    you may try

    if right(objFile,4)=".jpg" or right(objFile,4)=".gif" then
    Response.Write " : <img src=http://domain_com/image_file/"& objFile.Name & ">"
    end if

    an example code info at http://3w.ezer.com/asp/file/server.mappath.asp

    works fine here.

    as the example code showing
    you may narrow down images from countI<100 to countI<10 or countI<2

    and recheck your mappath and <img src=http://self_domain_com/image_folder/"& objFile.Name & ">"

    use self_domain_com same as it belongs , do not use other domains
