title: iphone photo maximum size
body: <p>i want to know there a limitation in size for an iphone to display an image? as the resolution of iphone is 320*480 px.  i am developing an app which fetches photos from an URL and that URL contains some photos os size > 600KB.So when i launch the app in simulator it behaves properly but in device the application crashes as soon as photos with higher resolution are displayed , and when lower resolution photos are displayed the app does not crash in the device.</p>
