It imported the thumbnails from flickr for me, but all the images it put into the images folder say this when I open in a text editor:
302 FoundFound
The document has moved here.
Apache/2.0.52 (Red Hat) Server at gq1.farm4.static.flickr.com Port 80
Plugin works great. Could use a simpler process for installing but I finally got it. My only REAL problem with it, is it doesn't pull the exif data.
Something else I'd like to see is the abilty to change already uploaded image's size.
