{img} allows you to easily process a graphic file through the phpThumb thumbnail generator.  Available parameters are any allowed by phpThumb

• 'src',  // source
• 'new',  // create new image, not thumb of existing
• 'w', // width
• 'h',  // height
• 'wp', // max width for portrait
• 'hp', // max height for portrait
• 'wl',  // max with for landscape
• 'hl',  // max height for landscape
• 'ws',  // max width for square images
• 'hs',  // max height for square images
• 'f',  // output image format (jpeg, gif, png)
• 'q',  // JPEG compression (1=worst, 95=best, 75=default)
• 'sx',  // left side of source rectangle (default = 0) (values 0 < sx < 1 represent percentage)
• 'sy',  // top side of source rectangle (default = 0) (values 0 < sy < 1 represent percentage)
• 'sw',  // width of source rectangle (default = fullwidth) (values 0 < sw < 1 represent percentage)
• 'sh',  // height of source rectangle (default = fullheight) (values 0 < sh < 1 represent percentage)
• 'zc',  /* zoom-crop. Will auto-crop off the larger dimension
          so that the image will fill the smaller dimension
          (requires both "w" and "h", overrides "iar", "far")
          Set to "1" or "C" to zoom-crop towards the center,
          or set to "T", "B", "L", "R", "TL", "TR", "BL", "BR"
          to gravitate towards top/left/bottom/right directions
          (requies ImageMagick for values other than "C" or "1")    */
• 'bc',  // border hex color (default = 000000)
• 'bg',  // background hex color (default = FFFFFF)
• 'bgt',  //
• 'fltr', /*filter system. See documentation 
• 'xto',  // EXIF Thumbnail Only - set to only extract EXIF thumbnail and not do any additional processing
• 'ra',  // Rotate by Angle: angle of rotation in degrees positive = counterclockwise, negative = clockwise
• 'ar',  /* Auto Rotate: set to "x" to use EXIF orientation
         stored by camera. Can also be set to "l" or "L"
         for landscape, or "p" or "P" for portrait. "l"
         and "P" rotate the image clockwise, "L" and "p"
         rotate the image counter-clockwise.   */
• 'aoe',  /* Output Allow Enlarging - override the setting for
         $CONFIG['output_allow_enlarging'] (1=on, 0=off)
         ("far" and "iar" both override this and allow output
          larger than input)   */
• 'far',  /* Force Aspect Ratio - image will be created at size
         specified by "w" and "h" (which must both be set).
         Alignment: L=left,R=right,T=top,B=bottom,C=center
         BL,BR,TL,TR use the appropriate direction if the
         image is landscape or portrait.   */
• 'iar',  /* Ignore Aspect Ratio - disable proportional resizing
         and stretch image to fit "h" & "w" (which must both
         be set).  (1=on, 0=off)  (overrides "far")   */
• 'maxb', /* MAXimum Byte size - output quality is auto-set to
         fit thumbnail into "maxb" bytes  (compression
         quality is adjusted for JPEG, bit depth is adjusted
         for PNG and GIF)   */
• 'down', /* filename to save image to. If this is set the
         browser will prompt to save to this filename rather
         than display the image   */
• 'phpThumbDebug', // 
• 'hash', //  depracated I think...
• 'md5s', /*  MD5 hash of the source image -- if this parameter is
         passed with the hash of the source image then the
         source image is not checked for existance or
         modification and the cached file is used (if
         available). If 'md5s' is passed an empty string then
         phpThumb.php dies and outputs the correct MD5 hash
         value.  This parameter is the single-file equivalent
         of 'cache_source_filemtime_ignore_*' configuration
         paramters   */
• 'sfn',  /* Source Frame Number - use this frame/page number for
         multi-frame/multi-page source images (GIF, TIFF, etc)   */
• 'dpi',  // Dots Per Inch - input DPI setting when importing from vector image format such as PDF, WMF, etc
• 'sia',  /* Save Image As - default filename to save generated
          image as. Specify the base filename, the extension
          (eg: ".png") will be automatically added    */
• 'nocache'//  ?
