[EXPLAINED] Error again(only by uploading high pixel pics)

[klaus1]

Hello,Klaus in Berlin still need your help

Problem describe
........................
 
When uploading high pixel pics I got the following warning.


Fatal error: Allowed memory size of 8388608 bytes exhausted at (null):0 (tried to allocate 1600 bytes) in /home/virtual/site140/fst/var/www/html/modules/coppermine/include/picmgmt.inc.php on line 195

I have oppened debug module and have found these info,hopfully could be useful.
...........................


Size and Time
Directive Local Value Master Value
max_execution_time 60 60
max_input_time 60 60
upload_max_filesize 2M 2M
post_max_size 8M 8M


Is this depend on my server? Or I ought to change some code again?
Look forwarding for your help,thanks!

You actually answered your own question here, your server(from debug) has a limit of post_max_size 8M and your pic is bigger than that. why would you want to have a pic this big for onscreen display anyway? it would probably take five minutes till I saw it on my 56k? connection

The file is only about 100K,but the pixel is high...(from a 2 megabyte photo)
Nowadays the popular type of digital camera has often 3 megabyte pixel.
Most users are usually too lazy to use software to minimize the pixel of the pics.
Really no rescue methode this time?


Otherwise I can find the uploaded pic with ftp programm,but it can not be displayed in the forum.
It seems that the server is still allowed to upload such file... :?:  :roll:

[gtroll]

8M is your limit but the server chokes on 100K? Change the setting in config of  Max size for uploaded pictures (KB) to 2048

[klaus1]

no use,I suspect the problem is cause too high pixel.
I can upload the same pic which with low pixel(it means low quality,but 400 k big) without any problem.
But if I just cut one corner from the high pixel file(even only 144k,better quality and small size) then I would have met the problem.


*with some image edit software we can change the both quality and size of the pictures
So many users of mine have met the same problem,only a 200k pic from a high pixel photo cannot be upload.

The file decompressed by the GD library and it will work in truecolor with it.

So how much memory uses your image without compression in truecolor ?

[klaus1]

what do you  mean?
From where can I read that date?
What can I still do?

[klaus1]

Can I change the post_max_size setting somewhere in the programm :?:

[DJMaze]

No you can't this limit is set in php.ini ask your provider for more memoryin php

I got the exact same problem!!

Fatal error: Allowed memory size of 8388608 bytes exhausted at (null):0 (tried to allocate 5120 bytes) in /home/virtual/site36/fst/var/www/html/modules/coppermine/include/picmgmt.inc.php on line 202

Directive Local Value Master Value
max_execution_time 30 30
max_input_time 60 60
upload_max_filesize 2M 2M
post_max_size 8M 8M

The size of pic i try to upload:
202Kb    1280x960

somehow the post came twice  :lol:

[DJMaze]

Let me explain (again) a compressed file (jpg/png) is decompressed by the GD library which causes a file that's far much bigger because every pixel is converted to a 32bit truecolor.

So when you use a large compressed picture, decompressed it will be damn big in PHP.

So for example in your paint app:
- set JPG compression to 0% and save the file. How big is it ?
- save the file in truecolor as BMP. How big is it ?

there are your answers
