dex].value
}

</head>
<body>
<%
' Create an instance of the FileSystemObject
Set MyFileObject=Server.CreateObject("Scripting.FileSy stemObject")
' Create Folder Object
Set
MyFolder=MyFileObject.GetFolder(Server.MapPath("/zad-alrida/images/produ
cts/"))
response.write(MyFolder)
'Loop trough the files in the folder
FOR EACH thing in MyFolder.Files
%>
<form name="mygallery"><p><select name="picture" size="1"
onChange="showimage()">
<option selected value="<%=thing.Name%>"><%=thing.Name%></option>

Boris Nikolaevich #2 Re: Display images name thrue drop down box
To help you think through the process, indent each line of code or HTML
according to what's happening. (You don't have to save your code with the
indentations if you don't want to, but it will help.
Here's an example of what I mean:
<snip>
...
'Loop trough the files in the folder
FOR EACH thing in MyFolder.Files
%>
<form name="mygallery"><p>
<select name="picture" size="1" onChange="showimage()">
<option selected
value="<%=thing.Name%>"><%=thing.Name%></option>
</select>
<img src="<%=thing.Name%>" name="pictures" width="99" height="100">
<% next %>
</form>
...
</snip>
Do you see how things don't quite match up? For example, the opening <form>
tag occurs inside your For/Next loop, but the closing tag occurs outside the
loop. Your <select> tag and <img> tag also are inside the loop. That means
as the code runs, you will get many forms (which won't work), many drop-down
lists with only one item, and many images--one for EACH file in your folder.
Now think about what you WANT to happen. You want one form, and one image,
but multiple options in your drop-down list. Without showing you the code
(the poeple in the groups made me learn on my own, too), you need to change
your loop so that only the <option> tags are repeated--one element for each
file in your folder.
One last note is that if you want the <img> to show the first picture by
default, you'll either need to use client script or add a variable to your
ASP that stores the name of the first file (e.g. replaces
src="<%=thing.Name%>" with src="<%=strFirstPictureName%>"
Hope that gets you started,
Boris

My modification of your code was NOT a suggestion on how to write the
function correctly, it was a suggestion on how to identify the error. Doing
that will be way more help than having someone post the correct code for
you.
Have you been able to get your script to work correctly? If you are still
having the same problem, I can post some additional advice.
