When I upload big images (4.2 MB) Intervention Image is throwing 500 Error...
private function resizeImage($path, $imgName){
$sizes = getimagesize($path.
I had the same issue and increasing upload_max_filesize
were not enough.
I also increased memory_limit to 256M
and restarted the server. Then images were working with Intervention.
[Above changes are in php.ini file]
You may want to change upload_max_filesize
and memory_limit
according to file capacity you are using.
