registerStreamWrapper problems when handling images (getimagesize) #1261
Description
Hi,
I used registerStreamWrapper for my project and all was fine with older release. Since the last one i had this problem:
when trying to get the image size for images on S3, sometimes values are completely wrong:
eg:
print_r(getimagesize('s3://mybucket/mydir/image.jpg'));
I get
Array
(
[0] => 160
[1] => 91
[2] => 2
[3] => width="160" height="91"
[bits] => 8
[channels] => 3
[mime] => image/jpeg
)
those values are wrong.
In fact if I use the php wrapper (thus calling the image with the public link) i obtain the correct values:
print_r(getimagesize('https://s3.amazonaws.com/mybucket/mydir/image.jpg'));
i receive
Array
(
[0] => 840
[1] => 476
[2] => 2
[3] => width="840" height="476"
[bits] => 8
[channels] => 3
[mime] => image/jpeg
)
This do not happens always, only with some images. But before the libs update it never happened.
Some other times, instead, trying to retrieve those size, i receive an error like this:
PHP message: PHP Warning: getimagesize(): corrupt JPEG data: 82 extraneous bytes before marker in /mycode/script.php on line TOT
PHP message: PHP Warning: getimagesize(): corrupt JPEG data: 95 extraneous bytes before marker in /mycode/script.php on line TOT
How could I help in solving this issue?
Thanks
Carmelo
