How can I save this image?

[jeddiki]

Hi,

I am using snapcasa.com to provide me with an image.

They encourage you to cache the images on your own server so I am trying to do that.

When I use this code to display the image it works fine:

<img src=\"http://snapcasa.com/get.aspx?code=9360&size=l&url=$Db_url\" width='300px' height='200px' alt='Thumbnail for $title_sht'>

Now, I want to save this image locally so I tried this:

$image_data = file_get_contents("http://snapcasa.com/get.aspx?code=9360&size=l&url=$Db_url");
file_put_contents($image_file, $image_data);

When I do the above I don't get the real image returned but only their
default "Unregister ed Domain" image.

This maybe an anti-hammer reaction because of the quick succession of my image requests.

So since I already have the image displayed using the <img src=
tag, is there a way to save this image locally ?

If not, maybe I should use the file_get_conten ts() function to get the image data in the first place ?

Would appreciate any input on this :)

Hey.

When you use the file_get_conten ts function, are you displaying the image in the <img> tag using the remote URL, or the local URL?

It should be something like:
[code=php]$url = "http://snapcasa.com/get.aspx?code=9 360&size=l&url= $Db_url";
$image_data = file_get_conten ts($url);
file_put_conten ts($image_file, $image_data);
echo "<img src='{$image_fi le}' width='300px' height='200px' alt='Thumbnail for {$title_sht}'>" ;[/code]

And be sure that the image URL is in fact what it should be. (Just print it before using it, to see if it is all OK.)

Hi Atli,

Thanks for your reply.

The way you did it is more logical as it requires only one call.

But for some reason the snapcasa.com site still does not accept
it.

I think their delivery script checks that my script or <img> tag
is coming from a website domain that I have registered with them.

I have registered my domain and IP address with them.

Maybe when I use the file_get_conten ts($url) method, it is anonymous and
therefore only gets back their "Unregister ed Domain" image - not the image that I want.

When I use the <img> tag with their address in it,
it works fine.

Any more ideas on how I can save the image ?

In theory it should possible to save the image after I have got it
and served it to my website - after all it is in my server's memory.

Just to recap - this works:

<img src=\"http://snapcasa.com/get.aspx?code=9360&size=l&url=$Db_url\" width='300px' height='200px' alt='Thumbnail for $title_sht'>

But this doesn't :

$url = "http://snapcasa.com/get.aspx?code=9360&size=l&url=$Db_url";
$image_data = file_get_contents($url);
file_put_contents($image_file, $image_data);
echo "<img src=\"$image_file\"  width='300px' height='200px' alt='Please wait while thumbnail loads ...'>";

And by "doesn't work" I mean that it does return an image, but not the one requested,
it delivers a standard "Unregister ed Domain" image.


Thanks.

That should not be the case. If the <img> tag version is meant to work on more than a single compute (which I assume it is?) then checking where the request is coming from and denying access based on that makes no sense. - It's the browser that requests the image, not the server, so that each person visiting your website would be requesting the image from a different, usually domain-less, IP address.

It's far more likely that the URL you use in your script is somehow malformed.
In your last example, before you call the file_get_conten ts() function, have you defined the $Db_url variable? If so, are you sure it is valid? - Try printing the $url, just to make sure it is as you expect it to be.

Hi Atli,

I have now changed the code to display the
url and then afterwards use the url in the img tag.

Like this:

$url = "http://snapcasa.com/get.aspx?code=9360&size=l&url=$Db_url";
$image_data = file_get_contents($url);
file_put_contents($image_file, $image_data);
echo "<img src=\"$image_file\"  width='300px' height='200px' alt='Please wait while thumbnail loads ...'>
<br>
<br><br>The Paydotcom Product Code: $Db_prod
<br><br>Image Url: $url
<br><br>
<img src=\"$url\"  width='300px' height='200px' alt='Please wait while thumbnail loads ...'>
<br><br>
<span style = \"font-size:18px; color:darkblue;\"><b>Customer Payments Schedule:<br>$price</b></span>

I think it proves that the url is fine:

The result can be seen for yourself:

Test Page

You will see the file_get_conten ts function attempt
in a box with just the ALT showing followed by the immage using the
same url but in the img tag.

I hope you can see a fault with my script ;-)

If not, how else can I save the file ?


Thanks for your help.

Any more suggestions on this one ...


I am still stuck :(

Just read the file contents and write them to your own file.

$fh = fopen( "http://snapcasa.com/get.aspx?code=9360&size=l&url=$Db_url", "rb" );
$fh2 = fopen( "myimage.img", "w" );
while( ( $content = fread( $fh, 1024 ) ) )
{
fwrite( $fh2, $content );
}
fclose( $fh );
fclose( $fh2 );

Note: allow_url_fopen must be turned on for the above code to work.
