Several issues trying to translate the Readme.md files with pandoc

[vonbrand]

pandoc Readme.md -o Readme.pdf chokes on some files:

07 uses ![](https://i.stack.imgur.com/N0KnG.png) to get an image, that doesn't work.

62 references the issues (here!), that gives a huge image that doesn't fit.

Attached two git patches (renamed as .txt as .patch can't be attached).
