wiki - Upload file doesnt work.

[Hummel Tom]

Hi,

I tried to upload a picture file called "graph.png" (note use of small 
letters), with the following parameters:

File: C:\Dokumente und Einstellungen\tom\Desktop\graph.png
Summary: example-graph for a two dimensional array
Using Windows and Firefox at the moment :(
