is it possible to download files straight to my web server?

Would it be possible to, for example, transfer a picture from photobucket straight to my web host without downloading the picture to my computer and then re-uploading via ftp?
Answer #1
use the remote upload
for example rapidshare one:
With Remote Upload you can copy files quickly and easily from other servers directly into your Premium sector.
You have currently saved 0 of up to 300 copy jobs.
A file should not be larger than 210,000,000 bytes (200 Megabytes).
This is a new queue system. We will start 5 downloads at the same time.
Insert link (http:// or ftp://)
