Quite often a jpeg image blob filesize will grow when reading back the image blob data!

eg.

$img = new Imagick();
$img->readImage($filename);

$sizeA = $img->getImageLength();
$blobdata = $img->getImageBlob();
$sizeB = $img->getImageLength();

Quite often sizeB will be greater than sizeA depending on the jpeg image being read
