Is there any way to discover if/how the file was renamed? I want to construct a URL out of the filename but I can't do that unless I know what the destination file was.
If this feature doesn't exist already, a simple idea would be to rename the original file to the same name as the uploaded version. That way I can use it in easily in a Growl notification, too.
Here is my rule (the shell script just copies the URL to the clipboard) if the above isn't clear. In fact I just used it to upload this image:

Thanks!
