  +As you may have noticed, there are a handful of interfaces that occur quite often when implementing functionality with appNG:
   
   * {appng}/org/appng/api/model/Site.html[org.appng.api.model.Site^]
   
  
positive.code: 
  
  ==== `URL` scope
  The `URL` scope has solely purpose of accessing URL parameters in a JSP with the <<appng-attribute,appNG:attribute>> tag.
  
  
  === `org.appng.api.model.Properties`
  
negative.code: <3> In that folder, create a new file.
  <4> Retrieve the binary data of the image.
  <5> Write the original image data to the `sourceFile`.
  <6> Retrieve a new {appng}/org/appng/tools/image/ImageProcessor.html[ImageProcessor^] using `sourceFile` as a source and defining the name of the target file (which will be located in the folder `imageCache`).
  <7> Resize the image to make it fit into a (imaginary) box with a size of 120x120 pixel (aspect ratio is kept!), set the quality to 80%, and finally return the target file.
