It's not a good idea to hold the selected images in memory by adding them to an array. These images are in general very memory intensive and can easily fill up the memory.

[arrimages addObject: CImage];

Possible solution:

Scale images

Scaling the images after retrieving them from the UIImagePickerControllerDelegate - imagePickerController:didFinishPickingMediaWithInfo: also helps reducing the memory footprint.

Save images to disk

Don't keep the images in memory, instead save them to the disk and get them from disk if needed.

iPhone - UIImagePickerController -> save the image to app folder
