I'm trying to make the img() my own size, as it's the factor that decides the size of specific images. But I'm not very experienced with php.
<?php img('thumbnail_medium'); ?>
I can change thumbnail_medium to thumbnail_large or just thumbnail, but anything except for that sets the size to its original.
I'm not too sure what value to put in there that'll work.
Help would be much appreciated, and thanks to everyone who has helped me in the past.
