title: How can I reduce the file size of a photographic background image without losing quality?
body: <p>I have a very large background image ~400k.  If I reduce the quality in Photoshop to say (4) it will shrink it down to ~180k - still big but much more manageable.  Are there any other good methods at reducing file size without losing a ton of quality?  My PSD for my background image is basically a giant collage - some of the pics have color and the rest are desaturated.  I'd love to save as black and white but need some of those color images.</p>
  
  <p>Thanks for any help! </p>
