It might be easier to create a JIRA issue and attach the images to the issue.

You can choose *not* to contribute the image (e.g. you might not have rights to the images) by clicking the appropriate box on the JIRA.

Hi Dirk,

  Can you please attach one of the PNGs in question?  I think this
mailing list posts attachments on the web. If you're worried about
privacy or intellectual property rights to the image, please just
email it to me at: [EMAIL PROTECTED]

Thanks,
  Charles.
