Error when uploading a jpg

dbibel March 3, 2012

I've tried to upload a jpg and received the following in the error.log -- I should say that I recently upgraded to Omeka 1.5:

"Something went wrong with image creation."

That's the important part of that error message. This means you have a problem with using ImageMagick to create thumbnails from uploaded images.

Your problem is (most likely) with one of the following:

  • The ImageMagick path you configured in Omeka's Settings panel (it should point to the folder that contains the convert program on your server)
  • Your actual ImageMagick installation (this is rarer, but sometimes people have ImageMagick installed in such a way that it doesn't actually work)
  • Permissions on your temporary directory. You need to be able to create files in "/tmp" on your server for ImageMagick to be able to create the thumbnails

John - thanks for the reply.
I've check #1 - the 'test' button returns 'OK'
2. Not sure how to test that.
3. There isn't now a '/tmp' folder on my site - where should it be? In the root, or in the 'home' folder of the 'omeka' install?

Again - thanks for the reply, appreciate the suggestions!

The "/tmp" folder isn't with the rest of your site, it's at the server's root (that's usually what a leading slash in a path name means).

So, where your site is at "/home/content/f/p/u/fpuu02052" from the server root, the folder I mentioned is just at "/tmp".

This is the server-wide temporary directory for your host, and it's where the thumbnails are generated and saved before they're moved to the Omeka archive directory.

For all three issues, it's probably best to check with your web host. They'll be able to confirm that you're using the right path for ImageMagick, that the ImageMagick installation is working correctly, and tell you about your permissions and the "/tmp" directory.

OK, made a request to my isp - they've been pretty good in responding in the past, so I'm hopeful.

thank you again for your suggestions!
