Thumbnails not created on w/XAMPP

I've installed Omeka 2.3 on OSX w/XAMPP v5.6.8. Imagemagick (convert) v6.9.0-0 is installed via Mac Ports in /opt/local/bin/ However, Omeka is not generating thumbnails of JPG files. Permissions on sub-directories of /files is 775.

I hate to bring up the nth version of the imagemagick thread (last time I was on these forums 3 years ago I had the same problem with MAMP) but I'm definitely stuck.

If you have the IMagick PHP extension, you could try switching to using that by changing config.ini. Right at the bottom of that file, uncomment this line by deleting the semi-colon:

; fileDerivatives.strategy = "Omeka_File_Derivative_Strategy_Imagick"

I fired up XAMPP again to try this and now I'm getting an unrelated 'Zend_File_Transfer_Exception' problem (which I hadn't had before). I'll need to look into this first.

Has anyone been able to install the current Omeka w/o issue on a current or recent version of either MAMP or XAMPP under OS X? Probably worth a separate forum post.
