merlyn's comment about the Location header is spot on, the RFC says that a Location header should use an absolute URI. That's no disaster, with the module URI (that comes with LWP, AFAICT, thus, I think, most perl installs should have it — at least, Bundle::LWP lists it), you can solve several problems at once, such as not having to have the images under the current directory (perhaps even chdir to it before you glob, if you have to). For example: 
use URI;
print URI->new_abs('../images/t-rex.jpg', 'http://www.example.com/home
+/');

[download]
produces:
http://www.example.com/images/t-rex.jpg

You must have noticed another problem with redirection: caching. The browser thinks, because that's what the server told it, that the location of the image is permanently moved to the URL it got back once. So next time, the browser won't ask again.

You can remedy that, at least on HTTP1.1, with a "moved temporarily" status header, status code 307. That way, next time, the browser will repeat the request.

You might have to find other solutions for browsers that only understand pre-1.1 HTTP, if those still exist.
