Problem with Imageview on deploying.

Hi all,

I successfully created an imageview for displaying some item-images.
However in simulator, all images are loading and in device, only some are dispalying...

I copied all the images to project folder (means all images are in same location).
Even my resources contains all the images too...

Why this difference between device and simulator???

Whether the size / dimension of the picture matters???

Please help...

Thanks...
