To convert png to jpg try this:
Get a file from a form input
do some stuff to separate off the extension then...
if($extension=="png")
{
$uploadedfile = $_FILES['file']['tmp_name'];
$src = imagecreatefrompng($uploadedfile);
imagejpeg($src, 'test.jpg');
}
similar if the input image is gif
or to convert e.g. jpg to gif use imagegif instead of imagejpeg
