ignore text because of echo´ing image? - php

Question

I´m drawing an image in PHP from another website, which works. And I´m getting info and from a webpage, which is working. But together it isn´t and only shows the image.
If I cut the picture part and put it at the end it gives an error.
(Use for example nickname Mazey if you need to check out how that JSON page look like)
Has it to do with combining file get contents and my curl function?
<?php
$profPic = json_decode( file_get_contents( 'https://api.kag2d.com/player/'.urlencode( $_GET['nickname'] ).'/avatar/s' ) );
if ( $profPic ) {
if ( isset( $profPic->small ) ) {
$profPic = $profPic->small;
$extension = strtolower( pathinfo( $profPic, PATHINFO_EXTENSION ) );
$content = file_get_contents( $profPic );
if ( $content ) {
header( "Content-type: image/".$extension );
echo $content;
exit();
}
}
} else {
echo "error";
}
$stats = json_decode(file_get_contents('https://api.kag2d.com/player/'.urlencode( $_GET['nickname'] ).'/status' ));
if ( $stats ) {
if ( isset ( $stats->playerInfo ) ) {
echo $stats->playerInfo->username;
} else {
echo 'Error';
}
} else {
echo 'Error';
}
?>

You are attempting to return two different HTTP responses in the same file. If you read the section for images, it does an exit() after printing the image data. This why it stops processing.
When I ran the URLs included in the source, the username returned is the same as the value in the $_GET['nickname']. Do you actually need to look this value up? It would work if you just returned the image.
A solution is to return a JSON document like your third party server is doing, and embed all the information in this. It is legal HTML to have image data as an URL, so the entire thing could be returned as single JSON document. HTML based example from the RFC2397
<IMG SRC="data:image/gif;base64,R0lGODdhMAAwAPAAAAAAAP///ywAAAA

Unlike email, noone seems to be developing multi-part mime responses inside HTTP. I did a quick google, but no useful results.
