I have a code which is working for me (see below),
But the textarea does not word-wrap, however I ask it nicely. I tried all I can find online, but not knowing PHP properly, it is a bit hard. I think I tried whatever there is for 'imagestring'. This piece of imagestring is stubborn, indeed. I thought I will trick it with css, nada. js, nada.
<?php
if(isset($_POST['submit'])){
$file_name = $_FILES['image']['name'];
$file_size = $_FILES['image']['size'];
$file_tmp = $_FILES['image']['tmp_name'];
$file_type = $_FILES['image']['type'];
move_uploaded_file($file_tmp,$file_name);
header ("Content-type: image/jpeg");
$string = $_POST['caption'];
$font = 12;
$width = imagefontwidth($font) * strlen($string);
$height = imagefontheight($font);
$im = imagecreatefromjpeg($file_name);
$x = imagesx($im) - $width;
$y = imagesy($im) - $height;
$backgroundColor = imagecolorallocate ($im, 255, 255, 255);
$textColor = imagecolorallocate ($im, 0, 0,0);
imagestring ($im, $font, $x, $y, $string, $textColor);
$a = imagejpeg($im);
}
?>
