I have posted a new build of Flump, which is an Adobe AIR based Flickr image downloader. There are AIR files for AIR 1.1 (Mac and Windows) and the Adobe AIR Linux Alpha.
The biggest change in this version is that the app now supports Flickr account authorization, and also enforces image license restrictions when not authenticated.
There are probably a few bugs in this release, so just post them here or on the Flump issue page.
You can find more information as well as download it from here.
