Well, yeah, basically no thumbnail image exists until you upload it. Additionally hotlinking is generally a bad idea unless you have the permission of the source. Basically what you're doing is stealing their image to display on your site, and using their bandwidth to do it. One of these days you'll open the page and see a "replacement - no - stealing - allowed" image in it's place when they figure it out and add hotlink protection.
