'压缩'错误与wordpress上的巨大图像一起工作

Question

I'm creating a site that has the possibility of drag a huge image resolution (6000x8000 72dpi saved for web, approx 2MB) on Angular+WP. The image upload but gives me an error and the crunch doesn't work and I need an intermediate size to show on other pages and the thumb to manage the back...any idea what's wrong?

I have tried the following:

1
Changed the values of my php.ini (on local and remote server)

memory_limit = 256M
max_execution_time = 900
upload_max_filesize = 20M
post_max_size = 24M

2
Created .htaccess on wp-admin with

<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>

3
Changed from ImageMagic to GD system

4
Checked folder permissions to be at 755

Thanks

Answer 1

Finally I solved it!

I was thinking that Imagemagik could be the problem and was the opposite, I had the GD library active so when I finally installed Imagemagik on the server and configure + the php.ini new values it let me upload big images and resize them automatically.
