Flickr Inkify
Flickr Inkify, sometimes called FlickrInkifier, is a Windows Live Writer Flickr plugin with a twist: it supports ink editing. That is, if your system has ink support.
With or without, the basic operation of Flickr Inkify is to retrieve images from Flickr. Like Simple Flickr Insert and unlike Flickr4Writer, images appear one by one in a small window. You can use previous/next buttons to navigate the image set.
If your system does have ink support then you can also write on the image or do some simple image processing. The result will be uploaded back to Flickr as a new image (Examples).
