Library seems to be failing on some files about fast-image-size HOT 9 CLOSED

I've actually invested quite a bit of time investigating this further and testing possible approaches with using streams, However, as remote files do not support seeking (reading at a specific offset) and one of the biggest impacts will also be the latency for remote files I'm inclined to agree.
So IMHO the quickest and yet best solution is really to just increase the maximum header size for JPEG files. I've also arrived at the point where I seriously have to question who came up with this mess of an image format. 🙃

What version of phpBB 3.2 and this library are you using? There were some issues with previous versions that could result in the mentioned issue.

I'm using PHPBB 3.2.2 (latest), not too sure about the library version, can't find version in code...

from fast-image-size.

Should be the latest version, according to the composer.lock: https://github.com/phpbb/phpbb/blob/release-3.2.2/phpBB/composer.lock#L348-L349

Right. So, the latest version is failing then. Please find links to images, that are failing, in the ticket description.

Thanks for the report. I was able to reproduce this issue and also circumvent it for now by increasing the max header size for JPEG to 250 kB. I think I'll have to reevaluate to use either guzzle or something simpler to get rid of this restriction of having to increase this setting everytime a bigger jpeg picture comes along.

Hi, I'm having the same problem with this image: https://www.notendiele.de/uploads/gallery/33.jpg

from fast-image-size.

@marc1706 Maybe easy fix (increasing the max header size by 2 or even better by 4) in the meantime?
The bug is quite old, images go ahead by quality/size and phpBB users are facing the issue more often 😃

Hi!
This problem was not solved. I'm facing this problem with PHPBB 3.3 b2 and Fast image size 1.1.5.
Impossible to post this image: https://scooterclub.by/tmp/P90505-140230.jpg. Even changing image size to 786432x1000000.
The result is : It was not possible to determine the dimensions of the image. Please verify that the URL you entered is correct.
Best regards.
