just have an answer, where does the jukebox get the posters from? does it get the info from IMDB?? and are you supposed to rename the files so that it easally can get the info??

The Jukebox gets it's posters from IMDB or theTVDB usually
You can supply your own and there are recommended naming conventions for files, TV series etc
Recommend you have a look at the wiki http://code.google.com/p/moviejukebox/w/list

i have now renamed all movies and copyed it from IMDB, but it wont dowload the poster, howcome? i renamed them after the guide

If you double click index.html on a PC, does your browser display the images for the movies?
If not, have you tried a clean build of the jukebox - deleting the index.html and jukebox directories, and re-running YAMJ. Also check the YAMJ log file for any errors

i can see the info about the movies but no picture, i made a ned thread instead because im new at this

Is there a guide to make custom poster/infos about the movies that yamj doesnt find?

Just picked up this thread again which I seem to have missed weeks ago.
This URL in the wiki
http://code.google.com/p/moviejukebox/wiki/NFO_Files#XBMC_NFO_movie_XML
will take you to the .nfo section of the Wiki - the XML file format allows you to enter data to manually populate the data on the move info page in YAMJ.

The artwork section of the wiki
http://code.google.com/p/moviejukebox/wiki/Artwork
shows you how to set up custom poster images

I have used the above successfully for a number of videos

THANKS!!
It;s works
