How to implement a pic server?

[eluser]rogierb[/eluser]
Why that complicated? Why not just one CI setup with DB in which you store the image data en FTP the image to the pic server? This way your pic server will be dedicated and your application server aswell

I don't see the need to mix seperate functionality.

so:
1: upload
2: store image data in DB (including image location)
3: store image in tmp dir
4: ftp image to pic server ( in specific location? )

Above odering might not be the best.
