I have some troubles with the function imagecreatefrompng(), in PHP.
I develop a website which has the goal to permit users to upload their own Sprite Comics (kinds of Comics made with ressources extracted from videogames, called sprites).
I want to display in their galeries some miniatures of their comics, so I use GD and, of course, imagecreatefrompng().
But it throw a fatal error with large images:
Fatal error: Out of memory (allocated 8388608) (tried to allocate 4545600 bytes)
The same error occurs even after setting the value of "memory_limit" via ini_set()...
After few hours of researches, it seems to be because of the resolution: imagecreatefrompng() can't manage images having more than 1 040 000 pixels...!
It's very very inconvenient, since I can't limit the size of comics sent by the users...
Do you know any tips to resolve this issue?
Thnaks in advance!
You need to ask your hosting provider to set more virtual memory. It's a setting in php.ini - memory_limit and shouldn't be problem to do it free. You are now on the most lowest value.
