how to extract img src from an external list

**sallam** · 09-24-2012 12:19 PM

I just noticed that the image ordering is a bit different than they should be..
Edit: ooops. Its the fault of the original website, not your script!

Is there a way to protect the php file from being used from outside domains?. I want to protect my server resources..

edit existing (in your www or public_html folder) or Create a new text file and save it as .htaccess with the following:
RewriteEngine On
RewriteCond %{HTTP_REFERER} !^http://(.+\.)?yourdomain/ [NC]
RewriteRule images.(php)$ http://i.imgur.com/qX4w7.gif [L]

replace yourdomain with your own domain and http://i.imgur.com/qX4w7.gif to whatever page you want to show to prevented requests.

Worked very nicely. I tried it from another domain and it showed no images. Thank you SABI sooo much for your time and help.

I want to ask you a different question. My 20 pages have parts with identical html code lines, is it possible to use one centralized file where I save those parts, then all the pages extract those parts from it? Sort of a template but only for specific parts of html not all the page content?.. because right now, every time I want to change a line of code, I have to do it repeatedly in each of the 20 pages..

Yes you can do that in PHP

using include() directive/function; for this you will need to convert those pages to PHP (or simly rename .html to .php) then you can import external file where ever you want to.

.
.
.
<body>

.
.
.
<?php include('common.html');?>
.
.
.

</body>
.
.
.

you can use html, js, css, txt, php etc...

my nick is ZABI by the way

Ooops.. sorry about that ZABI
So if say there are 5 repeated lines from line 3 to line 7, then 2 repeated lines from line 10 to 11, should I create separate common.html files for each group of lines, and type the include command twice in place of the 2 sets of lines? or use one common.html file for all the parts? and if so, how do I guide the pages to each part in the common file?
An example please?

**ZABI** · 09-25-2012 06:19 AM

you can have as many external files as you wish, you can also include a php file that has included another and so on.

for example you have a.php containing 5 lines for all your files.
b.php contains 3 lines to be used in 2 files,

so you can use <?php include('b.php');?>

where as b.php may contain

<?php include('a.php');?>
some other content

$find=array('Thumb','Photo_','../');

echo "var images=new Array();\r\n";
$i=1;

foreach ($tags as $tag) {
    $src = $tag->getAttribute('src');        
    if (@strpos($src,'ContentPhotos')!==false){
        echo "images[$i]='".str_replace($find,$replace,$src)."';\r\n";
        $i++;
    }
}
?>

ZABI, please help me. The site has changed the location of the images. Now the images' URLs are like this:

Code:

spinneys.com/Library/Images/Spinneys%20flyer0-01.jpg

and sometimes like this..

Code:

spinneys.com/Library/Images/Spinneys%20flyer01.jpg

What changes should I make to your script above please?

**ZABI** · 01-07-2013 01:49 PM

Well i think it should still work as expected.

what is the problem you are facing ?

**sallam** · 01-07-2013 04:39 PM

The script is no longer pulling any images.
The script was pulling images from their urls listed in a webpage:
spinneys.com/sites/Egypt/News.aspx?pageid=54

But now there is no webpage, and I have to pull the images from the directory where they are saved:
spinneys.com/Library/Images/
