Image resize not working in some cases on 5.2.0

[Alexander Obuhovich]

In most cases images are sized properly, but image I've attached didn't resize and is producing following errors in debugger:

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: gd-jpeg, libjpeg: recoverable error: Corrupt JPEG data: 359094 extraneous bytes before marker 0xd9 in w:\in-portal\core\units\helpers\image_helper.php on line 188

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: '.../system/images/Buddy on the porch.jpeg' is not a valid JPEG file in w:\in-portal\core\units\helpers\image_helper.php on line 188

At first I though image is broken, but it'd GD & libjpeg thinks what way. I can open that image on my PC using any program, even Photoshop.

Line, where error is happening says:

$src_image_rs = imagecreatefromjpeg($src_image);

I thought that I need to update JPEG library, but I already have latest version 6b from 1998 year.

After a little bit of digging I was able to find this https://bugs.php.net/bug.php?id=29878 bug report, that explained a problem in GD being too strict about reading a bit broken JPEG images.

This is the code that solves a problem (highlighted line):

error_reporting(E_ALL);

// 0 is the current behavior

ini_set('gd.jpeg_ignore_warning', 1);

$im = imagecreatefromjpeg($file);

Here is the task: http://tracker.in-portal.org/view.php?id=1370

Ready for testing.
