How To See If An Image File Exists

I'm building some dynamic image links based on if the image file exists. How can I check 'if files exists' using asp or javascript? I've messed around some with FileSystemObject but so far no success.

FileSystemObject To See If An Image Exists.

Just wondering if someone could look at this and see where I may be going wrong. The basic concept is to use FileSystemObject to see if an image exists. If it does, display the image. If not, display image does not exists message.

<%
Set fs=Server.CreateObject("Scripting.FileSystemObject")
strFilename = ="e:path oimageprodPixscienceTN" &
(RecordSet1.Fields.Item("ID").Value) & ".jpg"
If (fs.FileExists(strFilename))=true Then %>
<%=(Recordset1.Fields.Item("ID").Value)%>
<%
Else
Response.Write("No Image Available")
End If
set fs=nothing
%>

Check If An Image Exists On Another Server

Does anyone know how I can check to see if an image exists on another web host? I tried using the file system object but it didn't seem to work. I think my problem is that I have to check a URL instead of an actual file path to see if something exists there.

Testing To See If Image Exists Before Displaying It

I dont know if this is the right place to ask this but I have a database which contains shop details, each of which can have several images associated with it. In the database I am just storing the image paths, the actual images are held on a remote server.

I am able to grab the pathnames from the database and then use the following code to loop through the recordset displaying the associated image(s).

While NOT rs.EOF
Response.Write("<img src=""servernameImages" & rs.Fields(0) & """ width=""150"" height=""150"">")
rs.MoveNext

My question is, in the event of one of the images not being found, it just displays a red cross, is there any way of testing to see if the image exists before I try and display it?

Test If File Exists

I have a left menu that is accessed and displayed via XMLHTTP (it resides on the same server). Some sections of the web site don't have a "menu.asp", so a "Page Not Found" page is returned, which doesn't look great in the menu column.. Is there a way to know if a page exists before using xml.responseText to pull it?

When I Upload A New Image File

I use upload.asp (an open source file) to upload image file to a hosting folder, and save the file name to a field of database (I use mysql). But sometime (not all time) when I upload a new image file, I lost all the old value (old image file name) that saved in the field of database, the file name field in all old record are all changed to NULL, but the new file name is correctly saved into the right place.

Does any body know why it happened? Is it because the upload action or insert action? And "insert into" sentence can change old record value?
