Hello and thank you for welcoming me to this forum (sorry for my english, I'm french, but I'll try to be clear).
After searching in the topics, I perceive that this problem is not resolved. My hosting provider is OVH (share hosting), and when i write in SSH this command line [which convert] and [convert] i have this :
Welcome to Ovh
centreia@ssh1.20gp.ha.ovh.net:~$ which convert
/usr/bin/convert
centreia@ssh1.20gp.ha.ovh.net:~$ convert
Version: ImageMagick 6.6.0-4 2012-05-03 Q16 http://www.imagemagick.org

So ImageMagick seem be installing on my hosting share server. But i've a troubleshouting with omeka (the test bouton in omeka's admin interface for ImageMagick path don't detected a problem, but my derivatives are not generate). Here is my error log:
2014-03-18T18:46:58+01:00 ERR (3): exception 'Omeka_File_Derivative_Exception' with message 'ImageMagick is not properly configured: invalid directory given for the ImageMagick command!' in /homez.775/centreia/centre-iannis-xenakis-archives.org/omeka-2.1.4/application/libraries/Omeka/File/Derivative/Image/Creator.php:44

So I don't understand. Thanks for your answer.
PS : I read that the omeka 2.2 perhaps solve this problem about derivative ?
Many thanks
