Ok, but why on earth the same file.tiff hash_file('md5', 'file.tiff');
produces
constant values?
Thanx for the tip.

Report bugs about pecl's package to pecl please.
Tip: float are not an exact science and tiff can use floats.

Description:
$this->insecure = new Imagick("file.tiff");
$this->originalhash = hash('md5', $this->insecure->getimageblob());
$this->originalhash is always different, but file.tiff is always the
same.
Test script:
---
$ob = new Imagick("file.tiff");
$hash = hash('md5', $ob->getimageblob());
