That seems to work, I was not familiar with this method. I will use that since
I
don't even need to update my PHP version. Thanks!

hmm, how about (rfc 2397):
$extension = image_type_to_extension(exif_imagetype("data://image/;base64," .
base64_encode($bin_data)));

Description:
------------
It would be nice to have an exif_imagetypefromstring function to determine an
image type from a string without having to save the string to a file in order
to
use the exif_imagetype function.
There is a getimagesizefromstring function in PHP 5.4 but exif_imagetype is
supposed to be much faster as it only needs to look at the first couple of
bytes
of the string to determine the image type.
My problem is I can't really take advantage of the faster behavior because my
image data is in a string, not in a file.
Test script:
---------------
<?php
$extension = image_type_to_extension(exif_imagetypefromstring($bin_data));
// versus
$tmpfile = tempnam('/tmp', 'upload');
file_put_contents($tmpfile, $bin_data);
$extension = image_type_to_extension(exif_imagetype($tmpfile));
unlink($tmpfile);
