While working on
http://www.hifi-remote.com/wiki/index.p ... izer_Guide, I wanted to keep the screenshots files in the original, high-quality size, just having them slightly shrunken when the page was rendered. So I wrote
which, on my private test-wiki server worked as expected (shrinking the piccy to 800 pixels wide on display). However, on the wiki server here, I got the error message
Code: Select all
Error creating thumbnail: /usr/bin/convert: Unrecognized option (-thumbnail).
and empty output was generated.
If I may guess, it appears as if /usr/bin/convert is the program from
Imagemagick in a very old version. (The /usr/bin/convert on my Linux computer (Fedora 21) has a -thumbnail option.)
