Need to use the thumbnail flag with imagemagick. Gives it a huge performance boost and strips the metadata out of the file.

Be very careful with this one!

-thumbnail causes ImageMagick to embed "freedesktop.org Thumbnail Managing Standard" metadata into the output image. Such metadata includes the full local path (!). I found this by accident on our wiki (Mediawiki, which uses ImageMagick).

The thumbnail flag doesn't change the way Imagemagick creates a pixelmap of the complete image.
