ImageMagic Error while uploading image

Omeka S
1

Dear All,

I am fairly new to Omeka S. Today I tried to upload an image file - having first creating a collection and an object type (media) - but it won’t work. The image file is a jpeg of 1,2 mb and I can actually upload is as an asset separately. I logged the error and the output is in attachment. I do think it is a problem with the ImageMagic configuration.
I am using Omeka 4.2.0 freshly updated and all, installed from an installatron script provided by the hosting company I am using. Thank for all the help

I think I found it: the config of the thumbnails was apparantly faulty

It shoud have been like described here -Configuration Options - Omeka S User Manual

But instead of the default option:
],
‘thumbnailer_options’ => [
‘imagemagick_dir’ => null,

There was:
‘thumbnailer_options’ => [
‘imagemagick_dir’ => ‘/usr/bin/’,

So ultimately the path set to ImageMagic was wrong. Hope this helps others.

Hello! I am dealing with the same issue here running Omeka S 4.2.0. I’ve futzed with the local.config.php file multiple times, giving the ‘imagemagic_dir’=> path as both

null,

and

‘usr/bin/’,

No matter what I’ve tried, I can’t get thumbnails to generate. Clicking on the “Get ImageMagick version” tab on the System Information page also yields [Unable to execute command] every time.

Any chance someone could provide some clarity on this? Thanks.

Update to say that this is apparently an issue with Reclaim Hosting specifically. They want a different ImageMagick pathway, and the info can be found here:
