Image() URLs fail due to lack of ATTACHMENT_VIEW permissions, crashes WikiToPDF

same Problem here.

WikiToPdf plugin tries to get the images as user anonymous. I do not want to give WIKI_VIEW/ATTACHMENT_VIEW to the anonymous user!

LegacyAttachmentPolicy? denies anonymous performing ATTACHMENT_VIEW on <Resource u'wiki:Features?, attachment:grad.png'>

Please fix this, or give us a workaround.

I still get the following error: (I think this is due to the 401 - unauthorized) can you point me towards a solution? is this due to missconfiguration, or a bug?

(i had to replace all occurences of "http" with "tthp" for beeing able to post this)
