I would say, this is a really nice module. :) Originaly developed by guys in Antinomia solutions. I had to do few bug fixes, but then me and Matt (Antinomia) decided to improve it a little bit.
The main functionality will be getting content from arguments sent through _GET or _POST and fill it into fields (CCK or any default).
But that is not all of course. Guys in antinomia have developed a firefox extension, where you can click a button in your toolbar (same as you click on Go Back one page or Refresh buttons) on any web page you like. Then you can select an image, you want, and it will be sent straight to your predefined node with lets say imagefield on your drupal site.
But again we want to move it further, and create a firefox extension generator, so everyone will be able to create their own extension and link it to theirs nodes.
Stay tuned. ;)
