$icononsrc = $_FILES['iconoff']['tmp_name'];
$iconoffsrc = $_FILES['iconon']['tmp_name'];

$thumboff = PhpThumbFactory::create($iconoffsrc);
$thumbon = PhpThumbFactory::create($icononsrc);

$thumboff->adaptiveResize(200,151);
$thumbon->adaptiveResize(200,151);

$thumboffname = "uploads/".$_FILES['iconoff']['name'];
$thumbonname = "uploads/".$_FILES['iconon']['name'];

$thumboff->save($thumboffname, 'jpg');
$thumbon->save($thumbonname, 'jpg');

From the stack trace, when checking if the file exists and is readable

#1 [cut] ThumbBase.inc.php(110): ThumbBase->fileExistsAndReadable() 

an error is thrown

#0 [cut] ThumbBase.inc.php(172): ThumbBase->triggerError('Image file not ...') 

(bear in mind the stack trace appears in reverse order)

I would infer from this that the file name you are trying to convert either doesn't exist, or has a permissions issue. Ensure that the file exists and has appropriate read permissions.
