In your method where you want to increase the size, do:

CGRect newFrame = theImgView.frame;
newFrame.size.width += increaseInWidth;
newFrame.size.height += increaseInHeight;
theImgView.frame = newFrame;

note that the contentMode of the image view should be "Scale To Fill" or "Aspect Fill" if you want the image to get bigger, and not just the frame of the image view :)

Highlight can be done by placing a semi-transparent UIView (opaque = NO; alpha = 0.5) on top of the ImageView.
