Millisecond Forums

Here is my problem:
We have a picture rating experiment with many images, and the files far exceed the allotted server space that millisecond.com provides. So we put these images on another server, yet our calls to this server from our millisecond.com script results in errors stating that the file cannot be located. Based on the instruction guide, it doesn't explicitly say whether we can in fact call files from other servers when placing our main script on the millisecond.com server.
