What exactly do you mean, "partially downloaded" ? Do you say some are downloaded and some are not? Or did you mean every image is downloaded 90% but then aborts downloading?
If it's the first thing, then: Did you test this with multiple servers? Are some of them run by other people?
Note: some webserver do not allow hotlinking of images. They usually check the browser referrer and if it looks as if you're not watching the corresponding webpage then they won't deliver the image you're trying to access. Maybe that's the problem?
