What can be wrong?

Hi all,

I have a script so member try and upload photo so are 5-10MB and 5312x2988.

My problem is:
When a user upload photo so stay it only and loading on site and nothing more.

I have set this in php settings:
post_max_size: 500M
upload_max_filesize: 128M
memory_limit: 64M

Also try MANY others MB size without success.

What can be wrong?
