A quick function to automatically generate a multi line image from a string, with the image size automatically calculated from the string itself. 

<?php 

function multilineimage($string){ 

    // Probably not the best way of handling newlines, but bar OS9, doesn't really cause a problem 
    $string = str_replace("\r","",$string); 
    $string = explode("\n",$string); 

    $maxlen = 0; 
    foreach ($string as $str){ 
        if (strlen($str) > $maxlen){ 
            $maxlen = strlen($str); 
        } 
    } 

    // Set font size 
    $font_size = 4; 

    // Create image width dependant on width of the string 
    $width  = imagefontwidth($font_size)*$maxlen; 
    // Set height to that of the font 
    $height = imagefontheight($font_size) * count($string); 
    // Create the image pallette 
    $img = imagecreate($width,$height); 
    // Grey background 
    $bg    = imagecolorallocate($img, 205, 255, 255); 
    // White font color 
    $color = imagecolorallocate($img, 0, 0, 0); 

    $ypos = 0; 

    foreach ($string as $str){ 

        $len = strlen($str); 
        for($i=0;$i<$len;$i++){ 
            // Position of the character horizontally 
            $xpos = $i * imagefontwidth($font_size); 
            // Draw character 
            imagechar($img, $font_size, $xpos, $ypos, $str, $color); 
            // Remove character from string 
            $str = substr($str, 1);   
        } 
        $ypos = $ypos + imagefontheight($font_size);   
    } 

    // Return the image 
    header("Content-Type: image/gif"); 
    imagegif($img); 
    // Remove image 
    imagedestroy($img); 
} 

multilineimage("This is an image 
This is line 2\nLine 3 
Line 4"); 

?>
