title: print quality images with php and GD
body: <p>I need to take a photo someone has uploaded through a form, resize, merge with a high-res frame @ 300dpi and keep it all @ 300dpi for the best quality for print. </p>
  
  <p>is it possible to handle high-res images through GD and if so, could you provide some information on how? I have code that already does the resizing and merging, but i'm not sure if its going to work at the correct dpi.</p>
  
  <p>Thanks</p>
