I'm looking for a way to increase image upload size in Opencart 3 from 300kb to 3mb
I tried to change
oc_store/controller/setting/setting.php the 571 line in GH-repo from 300 000 to 3 000 000 to achieve approximate 3mb size.
$data['config_file_max_size'] = 300000;
Also I found a solution applicable to Opencart 2 only
In OpenCart 3 there is built in tool to change upload image size and there is no need to change the code:
Go to Admin -> System -> Settings -> Server -> Max File Size
One more tip: To change preview image size from 300x300 - go to:
admin -> Extension -> Extension -> Choose the extension type: Theme -> Product Image Thumb Size
