title: image button "save as" to save file from external servers php script
body: <p>I have a pictrures gallery on my server. The pictures are stored on diffrent external servers. On my server are placed the thumbnails only.
  How I can make a button "save as" in php so that a user can download a big picture file which is from external servers. I need a simple php script which can do download a jpg file cross all browser agents and from diffrent external servers. The button will be implemented inside html code. The button is a regular link formated in css style.
  So how to do it properly. Thanks.</p>
  
  <p>I would like also that the path of file should be send as a variable parameter to php script somehow.</p>
