imagemagick don't pass test

it's the first time that i use omeka. I'm studying this CMS to understand how it works. I have istalled CMS, but I can't run Imagemagick. I have istalled Imagemagick on my windows and it's works fine, but when I write "C:\ImageMagick\ImageMagick-6.9.0-Q16" CMS says that "The ImageMagick directory path does not work." I have done many test without results. Can anyone help? this is site

ok, after the night I understand many things. My webhosting is Aruba. I have read that Aruba has already installed in the server rootimagemagick. But when I insert /usr/bin this is error:
2015-01-02T10:55:45+01:00 ERR (3): exception 'Omeka_File_Derivative_Exception' with message 'Failed to execute command: /usr/bin/convert -version.' in /web/htdocs/

Can anyone help? Is this hosting problem or mine? Thanks

About installation on Windows - Omeka and imagemagick can run on Windows, but the imagemagick test will return false. However, Omeka will still process images correctly using imagemagick.

Regarding your second post, I'm running Omeka on a shared server as a test and the path to imagemagick is /usr/bin. Works fine.

Have you confirmed with the host that imagemagick is definitely installed on the server and that you have the path correct? I would confirm that first at least.

If the path is correct, perhaps you can raise this as an issue with the web host.

finally came the answer:
"the path is /usr/bin contact your CMS support"

the problem may come from the fact that Omeka is inserted in a subdirectory?
the url is

It looks like someone else has had the same problem with this host.

They have ImageMagick installed, but they block the PHP function Omeka uses to run it. As mentioned in that thread, you could ask the host to unblock that function (proc_open), ask them to install the Imagick PHP extension, or switch hosts.

It bothers me that Imagemagick is still used with Omeka when it is obvious even to blind Freedie that it causes enormous trouble. I am attempting to set up Omeka and have had the troubleshooters on my host working to solve the problem for a couple of days. If it don't work dump it. There are simpler ways of doing thumbnails and images using any number of propriety software, such as Photoshop. Crikey, even Google's Picasa will load your screen with thumbnails by the bucketfull. Why haven't you developers given us a way to do it ourselves? Don't you trust us?

In the vast majority of cases, ImageMagick -- or the newly introduced option to use the Imagick PHP extension -- works just fine. Limitations imposed by the server administration are a separate issue that we can't do much about. Picasa benefits from them controlling the server configuration, which we as open source downloadable software cannot do.

Like Picasa, Omeka needs an internal mechanism for associating the derivative images with the original, which is why we handle that creation step ourselves. Creating thumbnails in Photoshop and trying to upload them separately would break the connection.

Indeed, we do trust you. That's why we've provided a mechanism for developers to add more derivative strategies.

For your particular case, I'd say that if the troubleshooters can't find a solution that uses one of the methods John offered above, you might be left needing to find a new host more compatible with standards used in open source software.

I am sorry To trouble you agin about this issue. I got my host to do the unthinkable and open the proc what ever as the only means of getting Omeka to work. It works fine now although I have no idea if it is producing thumbnails as I got distracted only something else for the last couple of days. As for choosing between Omeka and my host I am afraid I would have dumped you rather than them.I am testing Omeka for someone and if I couldn't get it working they would have no hope, so you would have lost me. I still think imagemagick is a not very sensible way to deal with images as can bee seen my the endless trouble it gives people. And will give as I believe from some other forum it is about to be replaced in your hearts. I used Picasa as an example of the proliferation of thumbnails. I have used it and got annoyed with it because it seemed to want to take over my images-it is like an iTunes in that- and I dumped it in the next iteration of my computer upgrade. The fact that you can do something about imagemagick-I understand the strategy in using it-and don't makes me wonder about how useful Omeka will be in the long run for historical displays.
