Re: PHP Warning: imagettftext() expects parameter 2 to be double

Hi, Thank you for getting back to me, your the first. The array works fine ­ I have tested it using var_dump(). Attached are the two files ­ xml.test ­ this holds the array of the text blocks which is being parsed by image.php. Line 38 is the problem, if you comment around the foreach() statement and un-comment the commented lines you should see it working fine, its when its within the foreach statement when it errors.
