Hi all,
tried to fix a couple of wikis now and have some questions.

1) In the old wiki was a picture manager which i currently miss in the
new one. How could be overseen which pictures are available to delete
unused ones or upload new ones or relink existing ones ?

2) The syntax highlighting seems to be a little buggy. 
a) For example a

```bash
...
...

```
marks sometimes bash commands (in that specific case 'cd') in red, the
same command in another bash code tag in regular white, it seems a
little inconsitent.

b) Also in the same bash code highlighting sometimes line numbers
appears and the whole code block get out of the format.

c) Also in the same bash code highlighting some numbers e.g. '192.168'
disappears cause it uses the page background color. May this happens
also with perl or another language which i haven´t checked until now.


Some things from here.

Best,

Erik
