Changing the image URL after Upload

Yes, assuming I've understood your query.

In fckconfig.js set:

var _FileBrowserLanguage = '[whatever yours is]' ; // asp | aspx | cfm | lasso | perl | php | py

In editor/filemanager/connectors/[whatever yours is]/config.xxx set:

' SECURITY: You must explicitly enable this "connector" (set it to "True").
' WARNING: don't just set "ConfigIsEnabled = true", you must be sure that only
' authenticated users can access this file or use some kind of session checking.

Dim ConfigIsEnabled : ConfigIsEnabled = true

' Path to user files relative to the document root.
' This setting is preserved only for backward compatibility.
' You should look at the settings for each resource type to get the full potential

Dim ConfigUserFilesPath : ConfigUserFilesPath = "[your path]"

eg Dim ConfigUserFilesPath : ConfigUserFilesPath = "/ftproot/images/"

OK. I think we're both getting lost here. What, exactly, are you trying to do. A short description is good but dont spare words in your reply, just make it very clear please. I'll need to know what dialog your talking about and precisely what and where your "image path" needs to change - ie in the dialog, on the server? Given a closer look at your original post you seem to be changing the mine type as well. Really not sure what you want to achieve.
