Show image using file_get_contents

how can I display an image retrieved using file_get_contents in php?

Do i need to modify the headers and just echo it or something?

Thanks!

Solution 1:

You can use readfile and output the image headers which you can get from getimagesize like this:

$remoteImage = "http://www.example.com/gifs/logo.gif";
$imginfo = getimagesize($remoteImage);
header("Content-type: {$imginfo['mime']}");
readfile($remoteImage);

The reason you should use readfile here is that it outputs the file directly to the output buffer where as file_get_contents will read the file into memory which is unnecessary in this content and potentially intensive for large files.

Solution 2:

$image = 'http://images.itracki.com/2011/06/favicon.png';
// Read image path, convert to base64 encoding
$imageData = base64_encode(file_get_contents($image));

// Format the image SRC:  data:{mime};base64,{data};
$src = 'data: '.mime_content_type($image).';base64,'.$imageData;

// Echo out a sample image
echo '<img src="' . $src . '">';

exactly.

Send a header("content-type: image/your_image_type"); and the data afterwards.
