in reply to How to extract the images from a PDF?

I have no idea how to do it in PHP, but Perl can do it in three lines:
use PDF::GetImages 'pdfimages';
$PDF::GetImages::FORCE_JPG = 1;
pdfimages('/path/to/file.pdf');

[download]
You will then find the images in the same directory as the PDF-file.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
