Redmine clipboard_image_paste plugin

Paste (cropped) image from clipboard as an attachment.

  • uses pure client side JavaScript
  • attachment works for issues, wiki, news, files, documents, forums
  • image can be interactively cropped
  • tested only in Google Chrome, Mozilla Firefox and the last versions of Internet Explorer (11+)
  • translations: Bulgarian, Czech, English, French, German, Italian, Japanese, Korean, Polish, Portuguese (+ Brazil), Russian, Simplified Chinese, Spanish, Taiwanese Mandarin, Turkish




Known issues:

  • thumbnails using {{thumbnail}} macro will not be shown in exported PDFs
    (Redmine’s PDF export limit – see,
  • maximum attachment size is checked against BASE64 encoded image data (even
    smaller images than the maximum allowed attachment size can be rejected)
  • clipboard_image_paste’s ‘Add picture from clipboard’ command combines number
    of both regular files and pasted images for maximum number of attachments check,
    while Redmine’s original ‘Add another file’ counts only regular files
  • ability to copy&paste images from clipboard depends on browsers capabilities
    – some browsers don’t support all image formats in the clipboard
    (but PrintScreen + Paste usually works)
  • Redmine 2.5 and older: attached image will be visibile in exported PDFs only
    if RMagick is installed (this is a limit of PDF export in Redmine – alpha channel
    must be removed from png image)
  • see Compatibility section for incompatible plug-ins
