    v7 v8  
    2727 * What dependencies are we comfortable with?
    2828   * Preference for limiting it to the Python Imaging Library only.
    29  
     29 * Image Quality using PIL
     30   * PIL has some serious quality problems for 'professional quality' images
     31   * Metadata destruction issues with PIL (wiping IPTC data, ICC profiles, EXIF data for instance)
     32   * No Color Profile Support (or 'hard to deal with' Profile support)
     33   * PIL and Large Files (20 MB Tiffs for instance) in a Web Environment = Bad
     34   * Lots of Thumbs on a page (i.e. 20+)  .. In memory constant converting not so good for server performance ..
     35     * file caching is a must
     36   * Advanced Sharpening/Contrast enhancements for very small thumbs
     37   * SOLUTION:: ImageMagick .. and 'convert' (http://www.imagemagick.org/script/convert.php) (PyMagick is really not suitable for most things)
     38      * Yes! Command line, but in a 'web' environ .. separate fork to deal with Memory and _large_ files
     39      * use of 'convert' should at least be a setting option for those that want quality
