Hello,

You can enable those PHP modules by running to following commands:

yum install curl
yum install php-curl

Regarding the getimagesize function, I think that you need to enable allow_url_fopen in your php.ini file. To do that try the following:

• Run php -i | grep php.ini to find out the location of your php.ini file

• Edit the file with your favorite editor

• Look for allow_url_fopen and set it to true

Hope that this helps!
Regards,
Bobby
