title: sharpen image quality with PHP gd library
body: <p>not sure where but I came across as image hosting site that allows you to upload your image in a large format or to sharpen it.</p>
  
  <p>I personally do not recall or know of any functions of GD library to sharpen image which might just be a different word for quality being up-ed. </p>
  
  <p>If some one knows of a function to sharpen images please tell me since personally I am not aware of such functions neither in Image Magic and/or GD Library.</p>
