How to import images directly into the html code (base64)
A couple of months ago I received an interesting task - to create a small html application for iPhone. To be honest, for me that meant creating a small site with a specific size. Of course I was wrong. Together with couple of small bugs I had to deal with one other requirement - everything had to be in one html file. It was clear how to add the javascript and the css, but what about the images.The solution was to use base64 encoding. I wrote a small php script that accepts an image and shows me the equivalent in base64 string.
<?php
$base64 = "";
$css = "";
$tag = "";
if(isset($_FILES['f']['name'])) {
$file = rand(0, 10000000).$_FILES['f']['name'];
if (move_uploaded_file($_FILES['f']['tmp_name'], $file)) {
if($fp = fopen($file,"rb", 0)) {
$picture = fread($fp,filesize($file));
fclose($fp);
// base64 encode the binary data, then break It
// into chunks according to RFC 2045 semantics
$base64 = base64_encode($picture);
$tag = '<img src="data:image/jpg;base64,'.$base64.'" alt="" />';
$css = 'url(data:image/jpg;base64,'.str_replace("\\n", "", $base64).'); ';
}
}
}
?>
<html>
<head>
<title>Base64 img convert</title>
</head>
<body>
<form action="./index.php" method="post" enctype="multipart/form-data">
<input type="file" name="f">
<input type="submit">
</form>
The CSS code:
<textarea style="width:800px;height:100px;font-size:10px;"><?php echo $css; ?></textarea>
The HTML code:
<textarea style="width:800px;height:100px;font-size:10px;"><?php echo $tag; ?></textarea>
<?php echo $tag; ?>
</body>
</html>
Just browse your image and click "Submit Query".
P.S. base64 doesn't work in IE
