Create image data URIs using PHP

Instead of providing a traditional address to the image, the image file data is base64-encoded and stuffed within the src attribute. Doing so saves a network request for each image, and prevent exposure of directory paths. Please note that IE7 and below are not compatibles with data URIs.

Code Snippet:

// A few settings
$image = 'cricci.jpg';

// 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,'">';
