title: Attach metadata to image
body: <p>Assuming my question <a href="https://stackoverflow.com/questions/2039910/get-files-in-a-folder">here</a> gets answered what are the options to attaching meta data to an image in my thumbs folder?</p>
  
  <p>I thought of placing an xml file in the folder which contains the filename and then the description of it but feel this to be a little clunky.</p>
  
  <p>For various reasons I can't use a database in this project which is very limiting.</p>
  
  <p>Is there a way to write meta data to the jpg file?</p>
  
  <p>The problem i'm trying to solve is that I need to display the image along with a short description of what it is.  kinda like a caption if you like.</p>
  
  <p>Any thoughts would be very welcome.</p>
  
  <p>thanks.</p>
