Image Handler 5 (for v1.5.5 - v1.5.8) Support Thread

[lat9]

load_imageGD() - I wonder if rather than assuming the extension was correct if it would make sense (perhaps optionally) to do a getimagesize.
I see cases where images have a .gif extension but they're actually JPGs.

--> PHP Warning: imagecreatefromgif(): '/home/client/public_html/images/folder/l_699-902-016_2.gif' is not a valid GIF file in /home/client/public_html/includes/classes/bmz_image_handler.class.php on line 939.

I've seen those logs before, too. Rather than slow the image-processing down for everybody, I've told the site's back-office staff to fix the image.
