calling imagick_blob2image - undefined function error

[Bonzo]

I know nothing about Imagick but there is another section on the forum main page for that. Have a look and see if there is anything in there that looks similar to your code.
I would also check out the Imagick site for more info.

Imagick 2.x supports only the object oriented interface. Please use 0.9.x series if you need the procedural approach.
