As you might, or might not know, I have been quite busy with Flickr lately, especially with [[User:FlickreviewR]]. I have written two tools (or actually, one tool with two functions) with helps Commons users with images for Flickr.
The first is a database of all images reviewed images from Flickr: http://tools.wikimedia.de/~bryan/flickr/browse You can search on nsid, username, photo_id, link, and Commons image. The database contains over 28,000 images, which is over 70% of the total number of Flickr images on Commons :) [1]
Now the second tool is really handy (imho ;P). It allows you to easily upload images from Flickr: http://tools.wikimedia.de/~bryan/flickr/upload :) All images uploaded by this tool are guaranteed to be tagged under a free Creative Commons license at upload time. Hopefully this will make it easier to upload images from Flickr, reduce the number of copyvios and make sure that only hi res images are uploaded.
All images are still in beta; by using this tools you are subject to the Commons Licensing and Project scope policies, etc. etc.; Please report errors to [[User talk:Bryan]]. If you find any security bug in the upload part, the bot that performs the uploads and to be blocked is Flickr_upload_bot.
:D, Bryan
[1] I do have a database of more than 95% of all Flickr images, but a lot of them are unreviewed. Human reviewed images are daily added to the database.
