Redmine

I am planning to use redmine wiki to manage project design and test documents. I can put text, diagram, images on wiki, and they can be shown from wiki page, but if I want to export the contents, only pdf is a proper format to export, but in the pdf file, only text, diagrams can be shown, images cannot be shonw in the pdf file, only list the image name as attachement.

Is there any solution or plug-in helpint to handle this issue, we want to export wiki pages including pictures shown in the wiki page with pdf format.

Thanks much!!
