I have the current release of Omeka, running on a new Centos server. When I add a new item with a pdf file, it does not create the thumbnail for the item. I found this topic, Thumbnails for PDF files are not being created and looked at the stackoverflow solution which requires changing policy.xml in ImageMagick.
Here are the error messages I got from convert:
convert 0065f6a2a36eac3e9f4bf451fc1c57cc.pdf test.pdf convert-im6.q16: not authorized `0065f6a2a36eac3e9f4bf451fc1c57cc.pdf' @ error/constitute.c/ReadImage/412. convert-im6.q16: no images defined `test.pdf' @ error/convert.c/ConvertImageCommand/3258.
Loosening security like that doesn’t seem to me to be the best way to do things, especially on a server that supports more than just Omeka. Has anyone come up with other possible solutions?
Thanks for any help,
