  Hey all, looks like a great site. Anyone know how to check for file existence from within JavaScript? I'm building a Royo gallery for my own use and i'd like to be able to run it from a single script file. All I need is a way to check for the existance of a thumbnail, (yes I did try new file; .exists, dosn't seem to want to work) am I retarded, or is it not possible with JS?. Thanks for reading.

  you can't (at least you're not meant to be able ) check for existence of a file on the local machine using client-side scripting. but you can check for files on the server using JavaScript or VBScript within an ASP, or PHP. are you using javascript within an asp? if so i'll give u the code

  are you checking for the exitense of a file on the server or the client's local machine?

  Sorry 'bout that, what i'm doing is trying to manage a rather large and ever-growing number of images in varied catagories (everything from local news stills to wildlife photos to background textures) via thumbnails of the main images, and what i'd like to do is get the manager running locally then open it up for outside use (BTW, to answer your query, server-side). I would prefer to use JavaScript as I am far more adept at it's use, but I'll not turn down any way of making it work.
  

  
  Thanks again,
  Gary

  something like this might work:
  

  
  

  Code:

  <%
  Dim FileSystem
  Set FileSystem = CreateObject("Scripting.FileSystemObject")
  

  
    If FileSystem.FileExists("C:\WINDOWS\Notepad.exe") Then
       Response.Write "Notepad is installed on this server."
    Else
       Response.Write "Notepad is not installed on this server."
    End If
  %>

  
  

  
  hope that helps.
