    UIImage provides no obvious way of telling the memory of the underlying data. However we could use Core Graphics to give us the estimate. You could probably get an estimate of the memory occupied by an image by doing

    size_t imageSize = CGImageGetBytesPerRow(image.CGImage) * CGImageGetHeight(image.CGImage);

    But I suggest you don’t base any image management on this. You really don’t know how much memory you will have with you. Try to minimize how many images you’ve loaded into memory. Basically, optimize as necessary.
