Answer 1

Use this Regular Expression ~\/\image\/(.*?)\/~
<?php
$str=' Mario Ermito photos by sample.com Mario Ermito Latest News, Photos, Biography, Videos and Wallpapers [img]http://xyz.sample.com/image/4205476/600full-mario-ermito.jpg[/img][img]http://xyz.sample.com/image/4453948/600full-my-profile.jpg[/img][img]http://xyz.sample.com/image/427185/600full-eagle-eye-poster.jpg[/img][img]http://xyz.sample.com/image/1323868/600full-alexis-bledel.jpg[/img][img]http://xyz.sample.com/image/2505314/600full-monroe-lee.jpg[/img][img]http://xyz.sample.com/image/3300481/600full-cindy-crawford.jpg[/img][img]http://xyz.sample.com/image/1046646/600full-pitura-freska.jpg[/img][img]http://xyz.sample.com/image/4322305/600full-kristin-kreuk.jpg[/img][img]http://xyz.sample.com/image/4261476/600full-kang-so--ra.jpg[/img][img]http://xyz.sample.com/image/3386911/600full-summer-brielle.jpg[/img][img]http://xyz.sample.com/image/4663949/600full-the-closer-artwork.jpg[/img]';
preg_match_all('~\/\image\/(.*?)\/~', $str, $matches);
print_r($matches[1]);
OUTPUT :
Array
(
[0] => 4205476
[1] => 4453948
[2] => 427185
[3] => 1323868
[4] => 2505314
[5] => 3300481
[6] => 1046646
[7] => 4322305
[8] => 4261476
[9] => 3386911
[10] => 4663949
)

You need to adjust your regular expression:
$regex = '#sample\.com/image/([0-9]+)/#'
preg_match_all('#sample\.com/image/([0-9]+)/#', $str, $m);
print_r($m);
Expected output:
Array
(
[0] => Array
(
[0] => sample.com/image/4205476/
[1] => sample.com/image/4453948/
[2] => sample.com/image/427185/
[3] => sample.com/image/1323868/
[4] => sample.com/image/2505314/
[5] => sample.com/image/3300481/
[6] => sample.com/image/1046646/
[7] => sample.com/image/4322305/
[8] => sample.com/image/4261476/
[9] => sample.com/image/3386911/
[10] => sample.com/image/4663949/
)
[1] => Array
(
[0] => 4205476
[1] => 4453948
[2] => 427185
[3] => 1323868
[4] => 2505314
[5] => 3300481
[6] => 1046646
[7] => 4322305
[8] => 4261476
[9] => 3386911
[10] => 4663949
)
)
Now you'll need to keep in mind that PHP will return everything it matches including the undesired parts of the regex string.
From the PHP Manual:
http://www.php.net/manual/en/function.preg-match-all.php
Orders results so that $matches[0] is an array of full pattern
matches, $matches[1] is an array of strings matched by the first
parenthesized subpattern, and so on.
