[TYPO3-typo3org] Images in online manuals?

[Stig Nørgaard Færch]

Are there new rules for applying images to the manuals?
I see that some of the online manuals have some trouble displaying images.
In this manual for my extension:
http://typo3.org/documentation/document-library/extension-manuals/constant_editor/0.1.1/view/
Its not shown at all.

But in this manual, it's displayed all right.
http://typo3.org/documentation/document-library/extension-manuals/neeg_vcard/0.3.0/view/1/1/

What am I doing wrong?
