Need to edit container php.ini

Just a note on this, since the mention of "1.5MB" could lead troubleshooting down the wrong path, this likely isn't an issue of file size limits, but the PHP process becoming exhausted of memory during attempted thumbnail creation.
So often tangential to image file size, but depends on image compression.

Based upon what was previously done for increasing file size limits, might just need a php_admin_value[memory_limit] = 256M to double the default memory limit.

I change memory_limit = 512M in php.ini and problem is gone.

I change memory_limit = 512M in php.ini and problem is gone.

Can you validate with 256?, then will look at a change.
