title: image size limit on iPad?
body: <p>I develop a web-app and noticed that my zoom function is not working for some pictures and realized that apprently some pictures are resized. Check out these examples (tested on iPad2):</p>
  
  <p><a href="http://zoom-test.magent-server.de/bild1.html" rel="nofollow">http://zoom-test.magent-server.de/bild1.html</a> -> picture in gif-format shown in full size</p>
  
  <p><a href="http://zoom-test.magent-server.de/bild2.html" rel="nofollow">http://zoom-test.magent-server.de/bild2.html</a> -> picture in jpg-format originally in the same size, but reduced on iPad</p>
  
  <p>I can't figure out when a picture is reduced. Apparently with gif it does not happen but also not always with jpg. It also does not depend on the image size or resoultion. I tested images with smaller and bigger sizes than those in the examples, but I couldn't find a pattern.</p>
  
  <p>Is there any way to prevent image size reduction? Or at least a defintion so I know which pictures will be reduced and which not.</p>
