curl Authentication error on Images Only - php

Question

I am trying to get information from a XML Rest API.
I can get everything but not the images.
I can display all info, but when it comes on images I get 401 error
Failed to load resource: the server responded with a status of 401 ().
My username and password are correct. The only way to get the images display is if I login to this API in a different window. Then all images are displayed.
Am I doing something wrong ? Here is my php code:
function CallAPI($url){
$curl = curl_init();
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($curl, CURLOPT_USERPWD, "usr:psw");
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($curl);
curl_close($curl);
return $result;
}
$a = "query SQL";
$asd = $database->query($a);
while($row = sqlsrv_fetch_array($asd)){
echo $url = $row['url']; // I can get this data display
$row['hotel_name'];
$a = CallAPI($url);
$axml = new SimpleXMLElement($a);
$img_link = $axml->item->images;
foreach ($img_link->image as $value) {
echo "<img src='".$value->sizes->size[1]->attributes('http://www.w3.org/1999/xlink')."' class='img-responsive' />";
}

Answer 1

So your problem must be that this link need authentication as well. So try make the call for $value->sizes->size[1]->attributes('http://www.w3.org/1999/xlink') to pass user and pass.
So you code should look like this
while($row = sqlsrv_fetch_array($asd)){
$url = $row['url'];
$row['hotel_name']; // No use of this one, maybe you use it on your end
$a = CallAPI($url);
$axml = new SimpleXMLElement($a);
$img_link = $axml->item->images;
foreach ($img_link->image as $value) {
/*I am adding the link to a variable*/
$imgLinkFromValue = $value->sizes->size[1]->attributes('http://www.w3.org/1999/xlink');
$img = CallAPI($imgLinkFromValue );
/* Now if you still get a link just pass the variable */
echo "<img src='$img->**link or href or anything you get**' class='img-responsive' />";
}
UPDATE
If you getting text or symbols maybe you have to use base64_encode().
Try this :
$img = base64_encode(CallAPI($imgLinkFromValue ));
echo '<img src="data:image/jpeg;base64,' . $img . '" class="img-responsive" />'
You can always change the data inside src to png or gif, depends on what you need.
