Hi all, I don't think I'm quite understanding the solution provided. My problem is exactly, or close to, the original issue.

Here is the function code:

function profile($instance_url, $access_token){
        // ERRRRROOOOAAAAAARRRRRRR Section.
        if (!isset($access_token) || $access_token == "") { die("Error - access token missing from session!"); }
        if (!isset($instance_url) || $instance_url == "") { die("Error - instance URL missing from session!"); }
        //MAIN variables
        //set Access Token given by salesforce oauth/oauth_callback
        $access_token = $_SESSION['access_token'];
        $instance_url = $_SESSION['instance_url'];
        //set Url to use - Search variable is at end of line; q=
        $url =  $instance_url . '/services/data/v27.0/chatter/users/me';
        // START OF CURLOPT // BEGIN FORMING CURL COMMAND
        $curl = curl_init($url);
            curl_setopt($curl, CURLOPT_URL, $url);
            curl_setopt($curl, CURLOPT_HEADER, false);
            curl_setopt($curl, CURLOPT_HTTPHEADER, array("Authorization: OAuth $access_token"));
            curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
            curl_setopt($curl, CURLOPT_TIMEOUT, '5');
            
        //HANDLE THE RESPONSE
        $json_response = curl_exec($curl);
        $profile_response = json_decode($json_response, true);
        curl_close($curl);
        
        echo '<div id="profile">';
        echo '<a href="' . $instance_url . '/' . $profile_response['id'] . '">';
        echo '<span class="p_photo"><img src="'. $profile_response['photo']['smallPhotoUrl'] .'"/></span>';
        echo '<span class="name">' . $profile_response['name'] . '</span>';
        echo '<span class="commentcount">Comment Count: ' . $profile_response['chatterActivity']['commentCount'] . '</span>';
        echo '<span class="likereceived"> Likes Received: ' . $profile_response['chatterActivity']['commentReceivedCount'] . '</span>';
        
        echo '</a>';
        echo '</div>';
        
}

I get the same error for the image that artofbi got. The image only loads after I go directly to the image URL and load it in the browser, then the widget I'm building can see the image.

Can someone give me an example of using the bearer code? Also, is that actually a solution in my case? I don't see how that is going to resolve my issue... Shouldn't there be a way to set the mime type after I receive it? I hope someone can point me in the right direction.
