I am trying to install http://www.redmine.org/projects/redmine/wiki/PluginScreenshotPaste or Redmine 2.0.4, but, no luck.
Do somebody knows how to amend the plugin to work?
I've made a rework of the plugin because it wasn't compatible with Redmine 2.1.x
You can checkout it on my github account : redmine_screenshot_paste.
I haven't tested it on branch 2.0.x. Please, tell me if it works or post an issue on github.
