Display of Images On IPhone.

iOS likes .PNG better, but there is no reason it shouldn't work with JPEGs.

You can use this tool to rapidly create some iOS code that displays images to see if it works.

If you create a Canappi file like this and submit here it will return a fully functioning iPhone app that displays your image (this is how it works):

package com.yourcompany ;


layout imageLayout {
     image clickMe (80,50,200,200) {
        'mypicture.jpg' ;
     } 
}

view imageView {
     controls {
         imageLayout ;
     }
}

main anImageApp {
     navigationBar ;
     start imageView;    
     menu { imageView } }
}

You of course need to add your image file as a resource to the Xcode project that is returned.
