//
// Preparations
// ------------
// You will have to create the following directory in your Smarty root directory:
// images/cache/
// A public directory (available for browser) the plugin uses for its cached 
// images. Feel free to change the path in the plugin.
// Additionally the GD library is required.
// 
// Sample usage
// ------------
// {thumb file="images/visuals/rallyewm02/Rallye142.jpg" 
// width="150" link="false" html='class="img float"'} 
// 
// 
// Parameters/*{{{*/
// ----------
// file [string] (required)
//      The path to your original big-sized image.
// 
// addgreytohint [bool] (default: true)
//      Set to �false� to get no lightgrey bottombar.
// 
// cache [string] (default: images/cache/)
//      Set to your favorite cache directory.
// 
// cacheUrl [string] (default: images/cache/)
//      Set to your favorite cache url.
// 
// crop [bool] (default: true)
//      If set to �true�, image will be cropped in the center to destination width and 
//      height params, while keeping aspect ratio. Otherwise the image will get resized.
// 
// dev="dev" - string : default=""
//      for development to ignore caching of the image
//      and generate each time a new image
// 
// extrapolate [bool] (default: true)
//      Set to �false� if your source image is smaller than the calculated thumb and 
//      you do not want the image to get extraploated.
// 
// frame [string]
//      A PNG image which is used to create a frame around the thumbnail. This image 
//      will be sliced into 3x3 blocks therefore the image dimensions have to be a 
//      multiplier of 3. An example image (33px x 33px) is 'thumb_border.png'
// 
//      Please note: For performance reasons the frame image will not be checked for 
//      modification.
// 
// getcachefilename [boolean] (default=false)
//      Returns only the filename of the cached thumbnail. No image will be returned.
//
// height [int] (default: 100)
//      The height of your thumbnail. The width (if not set) will be automatically 
//      calculated.
// 
// hint [bool] (default: true)
//      If set to �false� the image will get linked but will not have a lens-icon.
// 
// html [string]
//      Will be inserted in the image-tag. Useful, to align text around the thumbnail 
//      or to insert the alt-paramter or to...
// 
// legend="your text" - string : default=""
//      Text which should be printed as a legend at the bottom of the image
// 
// link [bool] (default: true)
//      If set to �false� the image will not get linked and not have a lens-icon.
// 
// linkurl [string] (default: set to �original image� )
//      Set to your target URL (a href="linkurl").
// 
// longside [int] (default: not set)
//      Set the longest side of the image if width, height and shortside is not set.
// 
// overlay [string]
//      A PNG image which is used to create an overlay image. The position will be 
//      determined by �overlay_position�.
//      Please note: For performance reasons the overlay image will not be checked 
//      for modification.
// 
// overlay_position [int] (default: 9)
//      The position of the overlay image. Can be an integer from 1 to 9. 
//      Here the positions:
//      1 2 3
//      4 5 6
//      7 8 9
// 
// sharpen [bool] (default: true)
//      Set to �false� if you don't want to use the Unsharp-Mask. Thumbnail creation 
//      will be faster, but quality is reduced.
// 
// shortside [int] (default: not set)
//      Set the shortest side of the image if width, height and longside is not set.
// 
// type [int]
//      The output file format. Set to 1 for GIF, 2 for JPEG and 3 for PNG. If not 
//      set, the source file format will be used.
// 
// quality="80" - int : default="80"
//      quality of the generated jpg image
// 
// width [int] (default: 100)
//      The width of your thumbnail. The height (if not set) will be automatically 
//      calculated.
// 
// window [bool] (default: true)
//      Set to �false� if you don�t want to open original image in a new window.
