So looking around this forum, i can't seem to find a way to make plugins that are not just effects. I use paint.net for my main editor for all sorts of images and i would like to make an easy way to share the work i am doing. There is a fantastic image sharing site called min.us which has great API, and i was thinking it would be great to make a plug in that allows you to export the image to the site. Can any one point me in a direction for this? Also, this might turn into a class project.
