Well, you have three conditions there that could be causing it to fall through

if (($ext == "jpg") && ($_FILES["uploaded_file"]["type"] == "image/jpeg") && ($_FILES["uploaded_file"]["size"] < 350000)) {
if (($ext == "jpg") && ($_FILES["uploaded_file"]["type"] == "image/jpeg") && ($_FILES["uploaded_file"]["size"] < 350000)) {

Have you checked them all individually? This is just part of basic debugging. Use echo, var_dump(), or assert() statments to check these expressions individually.

Example of using assert()

<?php
// Active assert and make it quiet
assert_options(ASSERT_ACTIVE, 1);
assert_options(ASSERT_WARNING, 0);
assert_options(ASSERT_QUIET_EVAL, 1);
 
// Create a handler function
function my_assert_handler($file, $line, $code)
{
    echo "<hr>Assertion Failed:
        File '$file'<br />
        Line '$line'<br />
        Code '$code'<br /><hr />";
}
 
// Set up the callback
assert_options(ASSERT_CALLBACK, 'my_assert_handler');
 
$a=1;
$b=2;
 
// Make an assertion that should fail
assert ($a==$b);
 
?>
<?php
// Active assert and make it quiet
