Best regards.

Example URL?

Hi erAck
There's no public access to this.
Can I send you a downloaded image instead ?

But today I have no possibility to download. I have an error message instead :
URL :http://192.168.0.155/piwigo/action.php?id=55183&part=e&download

Warning: Cannot modify header information - headers already sent by (output started at /volume2/web/piwigo/action.php:225) in /volume2/web/piwigo/action.php on line 231

And it weird, becaus this error doesn't happen on every image I try to download. I can download other images (but still impossible to open then)

It's (only) a warning message, but that may also be the problem for downloaded images because some PHP message may have crept into the output and is prepended to the image header.

Either disable displaying deprecated and warning messages (because it effectively may break functionality of a page even if nothing else is broken), in local config

$conf['show_php_errors_on_frontend'] = false;

or fine tune message classes to display, see [Forum, post 183126 by erAck in topic 31852] Menubar tags issue after 12.2.0 upgrade, or better, log to file instead.

Thank you. I'll check this !

AnthonyS · 2024-04-10 14:01:58

Well my problems are still here.
I put the log script you suggested to in my local/config/config.inc.php

A log file was created (it contains some php errors from Batch Downloader plugin, some errors when I sync new images), but the php warnings I mentioned before are still here (and just for one specific image, for now).
And the other images I download are still unopenable.

Please upload such failing image somewhere, e.g. gofile.io or postimages.org or imgur.com, and link here.

AnthonyS · 2024-04-10 15:00:17

Here I put 2 images that fail

Thanks again for your time

Sorry, but the uploaded image is not an image. Checking for file type reveals "data" but not a .jpg image.

AnthonyS · 2024-04-11 08:01:57

@OHappyDay I assure you it should be one, because when I directly download from the NAS where the images are stored, the image is good to see.

Here I added the one of the original one : *****

So piwigo seems to alter the image when you download it from it...

Perhaps should I do a clean install of piwigo with the latest version ?
Is it possible to do this and keep some informations ? (users, groups, tags, ...) ?

erAck · 2024-04-11 13:47:27

The failing images have a 0x0a LF linefeed character prepended. That very much reminds of [Forum, topic 30939] Images truncated after upgrade to 11.1 and [Github] Piwigo issue #1297 and https://github.com/Piwigo/Piwigo/pull/1620

OHappyDay · 2024-04-11 13:52:03

Hi,

I compared the two images with a HEX editor. The difference is the very first byte. There is an extra byte 0A in the newer (broken) file. When I remove this byte and save it the file is recognized as an image properly.

I don't know where this extra byte comes from and is injected into the file.

@AnthonyS: out of curiosity, what are the last 10 lines of your action.php file?

AnthonyS · 2024-04-11 15:13:29

@erAck
Here are the last lines :

Code:

// Looking at the safe_mode configuration for execution time
if (ini_get('safe_mode') == 0)
{
  @set_time_limit(0);
}

// Without clean and flush there may be some image download problems, or image can be corrupted after download
if (ob_get_length() !== FALSE)
{
  ob_flush();
}
flush();

@readfile($file);

?>

Seems to be the same content as the version in the downloadable installation files

@OHappyDay
Thanks for having a look. That's weird.
