By mistake I uploaded a too-large image using ME 2.0, and not knowing how to delete the image from my server using ME, I used CyberDuck and deleted via FTP.
So, now I need ME to re-scan the /image folder on the server because now it shows images that aren't actually there; and I wonder if there is a way to delete images uploaded via the ME Media Manager?
Recently I submitted a construction budget to a client and 'forgot' a $300,000 item!
There's another similar thread, though, so it looks like you haven't figured out how exactly to synchronize what ME knows about the remote folder. Isn't this a pretty simple FTP command?
Now you know just how little I understand about programming, I suppose :-)
