What are base64 equivalents for images?

Question

PHP

What's the problem: now I'm making an application that takes pictures and sends them to the backend (php). After processing, they are base64 encoded and sent back to the frontend. The problem is that some pictures are not displayed. Please advise what can be done

Answer 1

If correctly converted to Base64, they will all be displayed!

$files = array_slice($argv, 1);
foreach ($files as $file) {
   $picture = file_get_contents($file);
   $size = getimagesize($file);
   // base64 encode бинарные данные, а затем разбить его на фрагменты в соответствии с семантикой RFC 2045
   $base64 = chunk_split(base64_encode($picture));
   echo '<img src="data:' . $size['mime'] . ';base64,' . "\n" . $base64 . '" ' . $size[3] . ' />', "\n";
}

//This code is from official PHP.NET website

function base64_encode_image ($filename=string,$filetype=string) {
    if ($filename) {
        $imgbinary = fread(fopen($filename, "r"), filesize($filename));
        return 'data:image/' . $filetype . ';base64,' . base64_encode($imgbinary);
    }
}

.logo {
    background: url("<?php echo base64_encode_image ('img/logo.png','png'); ?>") no-repeat right 5px;
}

<img src="<?php echo base64_encode_image ('img/logo.png','png'); ?>"/>
