I don't have a asp example but I could send a php example if you would like.

Assuming that you allready have populated the json and u just want to save. Assuming that you have folder rights

here is an function that saves the image url to local file.

Response.Write SaveImage2LocalSystem("http://i.stack.imgur.com/rxByL.gif",".","myfile.gif")
'returns true or false


Public Function SaveImage2LocalSystem(ByVal ImageURL, ByVal DestinationFolder, ByVal ImageName)
    
    'constants
    Const adTypeBinary = 1
    Const adSaveCreateOverWrite = 2
    Const adSaveCreateNotExist = 1
    
    'declare
    Dim http , fso , Stream
    Set http    = CreateObject("Msxml2.ServerXMLHTTP")      'downloads
    Set fso     = CreateObject("Scripting.FileSystemObject")'directory
    Set Stream  = CreateObject("ADODB.Stream")              'saves
    
    'do the request
    http.open "GET", ImageURL,False
    http.send()
    
    'avoid error
    If http.Status >= 400 And http.Status <= 599 Then
        Response.Write "Error Occurred : " & http.Status & " - " & http.statusText
        SaveImage2LocalSystem = False
        Exit Function
    End If
    
    'Load BinaryData to Object
    Dim image : image = http.responseBody
    
    'convert the folder to real path
    DestinationFolder = Server.MapPath(DestinationFolder) & "\" '. or / will do
    
    'check and create
    If Not fso.FolderExists(DestinationFolder) Then fso.CreateFolder(DestinationFolder)
    
    'Save stream To File
    Stream.Type     = adTypeBinary
    Stream.Open
    Stream.Write image
    Stream.SaveToFile DestinationFolder & ImageName, adSaveCreateOverWrite
    Response.Write DestinationFolder & ImageName
    
    'or view
    'Response.BinaryWrite http.ResponseBody
    
    'close objects
    Set fso     = Nothing
    Set http    = Nothing
    Set Stream  = Nothing
    
    'return true or whatever
    SaveImage2LocalSystem = True
End Function

@Dale, I would like to see the PHP example :)

Here is my example:

You need to ensure each of the folder structure are created for each images.

$myimg1 = array('bIg5Hv4FZn9210BIO2wJ36MOjMF.jpg', 'aQpXLhmXQW69OaXsX6uv9F3zsuR.jpg');


 $original = "images/themoviedb/p/original";
 $w45 = "images/themoviedb/p/w45";
 $w92 = "images/themoviedb/p/w92";
 $w130 = "images/themoviedb/p/w130/"; 
 $w154 = "images/themoviedb/p/w154/";
 $w185 = "images/themoviedb/p/w185/";
 $w780 = "images/themoviedb/p/w780/";


foreach($myimg1 as $key => $value){

    $i = $value;
    if(!empty($i)){

        $fullpath = $original."/".basename($i);
        if(!file_exists($fullpath)){
            $originalImage = "http://image.tmdb.org/t/p/original/".$i;
            image_save_from_url($originalImage,$original);
            echo "Image original saved ". $fullpath ;
        }
        else { echo "Image original exist ". $fullpath; }

        $fullpath = $w45."/".basename($i);
        if(!file_exists($fullpath)){
            $w45Image = "http://image.tmdb.org/t/p/w45/".$i;
            image_save_from_url($w45Image,$w45);
            echo "Image w45 saved ". $fullpath;
        }
        else { echo "Image w45 exist ". $fullpath ; }

        $fullpath = $w92."/".basename($i);
        if(!file_exists($fullpath)){
            $w92Image = "http://image.tmdb.org/t/p/w92/".$i;
            image_save_from_url($w92Image,$w92);
            echo "Image w92 saved ". $fullpath ";
        }
        else { echo "Image w92 exist ". $fullpath; }

        $fullpath = $w130."/".basename($i);
        if(!file_exists($fullpath)){
            $w130Image = "http://image.tmdb.org/t/p/w130/".$i;
            image_save_from_url($w130Image,$w130);
            echo "Image w130 saved ". $fullpath;
        }
        else { echo "Image w130 exist ". $fullpath; }


        $fullpath = $w154."/".basename($i);
        if(!file_exists($fullpath)){
            $w154Image = "http://image.tmdb.org/t/p/w154/".$i;
            image_save_from_url($w154Image,$w154);
            echo "Image w154 saved ". $fullpath;
        }
        else { echo "Image w154 exist ". $fullpath ; }

        $fullpath = $w185."/".basename($i);
        if(!file_exists($fullpath)){
            $w185Image = "http://image.tmdb.org/t/p/w185/".$i;
            image_save_from_url($w185Image,$w185);
            echo "image w185 saved ". $fullpath ;
        }
        else { echo "Image w185 exist ". $fullpath ; }
    }   
}

function image_save_from_url($my_img,$fullpath){
    if($fullpath!="" && $fullpath){
        $fullpath = $fullpath."/".basename($my_img);
    }
    $ch = curl_init ($my_img);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
    curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
    $rawdata=curl_exec($ch);
    curl_close ($ch);
    if(file_exists($fullpath)){
        unlink($fullpath);
    }
    $fp = fopen($fullpath,'x');
    fwrite($fp, $rawdata);
    fclose($fp);
}

If you need any help let me know. I am using someone Image_save_from_url() function. Sorry that I couldn't give credit to the person I got it from.

Dale.

Thanks Dale, I'm having problems getting the images using AJAX and json

No problem. Sorry there was some format issues with my post. I have fixed it. Hope that helps.

Thanks Dale
