Hi Jaime ,
I would like to add some more details (5.10.0 Xmaxima on Windows 2000):

I created two files which include graphics: 
'erste_Schritte.html' and 'erste Schritte.html', both in folder 'G:\Projekt'
I pasted in the paths in different ways and also tested the reload button (which is useful for 
developing these html files):

1.
file://G:/Projekt/erste_Schritte.html
--> loaded correctly
Button Reload --> loaded correctly

2.
file://G:/Projekt/erste_Schritte.html  (followd by space character)
--> file://G:/Projekt/file://G:/Projekt/erste_Schritte.html 
file loaded, but graphics not found
Button Reload --> 
file://G:/Projekt/file://G:/Projekt/file://G:/Projekt/file://G:/Projekt/erste_Schritte.html 

3.
file://G:/Projekt/erste Schritte.html
--> file:/C:/PROGRA~1/MAXIMA~1.0/share/maxima/510~1.0/xmaxima/file://G:/Projekt/erste 
Schritte.html
file loaded, but graphics not found
Button Reload --> 
file:/C:/PROGRA~1/MAXIMA~1.0/share/maxima/510~1.0/xmaxima/file://G:/Projekt/file:/C:/
PROGRA~1/MAXIMA~1.0/share/maxima/510~1.0/xmaxima/file://G:/Projekt/erste 
Schritte.html

4.
file://G:\Projekt\erste_Schritte.html
--> file://G:\Projekt\erste_Schritte.html
file loaded, but graphics not found

5.
file://G:\Projekt\erste Schritte.html
--> file:/C:/PROGRA~1/MAXIMA~1.0/share/maxima/510~1.0/xmaxima/file:/G:\Projekt\erste 
Schritte.html
file loaded, but graphics not found


Hope you can figure out, whats going on.
