luceos MartianRoleplay the best thing to do is google installing php extension gd on <your operating system and operation system version>; so installing php extension gd on windows 10 for instance.
Spooonky MartianRoleplay you have to check whether the GD extension is available in the ext folder of your php version. If it is there, check whether you can find #extension = gd in php.in and remove the # before that.
