Ticket #4043 (new defect)

Description

In the PDF the links on images should be improved, with one enhancement and one defect-fix:

Enhancement

In the Wiki-output, the links point to the raw attachment (raw-attachment/wiki/[page name]/[image name]. In this case, it would be better to link to the "attachment page" in the wiki (attachment/wiki/[page name]/[image name]) so that the image is viewed in context and in the browser rather than having to be downloaded and saved or viewed with a local image editor.

Defect fix

Additionally, in single-page output, the links on images point to wiki/[image name] rather than attachment/wiki/[page name]/[image name] and so clicking on the image in the PDF gets a "describe [image name]" page rather than the image. This should behave as for wiki output (with the suggested enhancement!).
