title: Smaller Images from Picasa
body: <p>Does anyone know if there is a way to get a list of <em>all</em> of the image sizes that picasa is hosting?</p>
  
  <p>I've been using google's gdata java library for picasa, and I'm able to get a list of thumbnails ranging in size (3 in all of the cases that I've seen), and the full, original posted image - all from the PhotoEntry object.</p>
  
  <p>However, I notice that when you browse picasaweb.google.com, it also has a large, but possibly not full size image that's suitable for displaying on screen.  For example, an image loaded at 1600x1200 has another image at: 912x684.  But this image doesn't appear anywhere PhotoEntry (or in the underlying feed XML - at least for the way I'm querying).</p>
  
  <p>I notice that the url is almost the same (but introduces 's912' indicating the size), e.g.:</p>
  
  <p><a href="http://lh5.ggpht.com/_0WaNZR9hJtU/Sq0P86tsVdI/AAAAAAAAAIo/6fGDYaO--Eg/s912/P1030046.JPG" rel="nofollow noreferrer">http://lh5.ggpht.com/_0WaNZR9hJtU/Sq0P86tsVdI/AAAAAAAAAIo/6fGDYaO--Eg/s912/P1030046.JPG</a></p>
  
  <p>With enough examples, I could probably guess the generated sizes, and hack the url.  But I'm hoping that there are other ideas - or that I'm overlooking something easy.  Probably should post to a Google forum, but this site is more fun.</p>
