So I’m not entirely sure the correct method of doing this, so Nathan Rice, if you’re out there, let me know if you want to take this for your own!
WP-Cycle is a great plugin that just simply lets you upload images into a jQuery-based image slider for use in a WordPress page, theme, whatever. What I’ve done is added some functionality to the plugin that adds left/right arrows, as well as adding support for the scrollHorz, which is one of the default options from the original jQuery Cycle plugin. It’s nothing huge, but check out the code below, and if you like it, replace the wp-cycle.php file in the WP-Cycle plugin folder.
And Nathan, thanks for the great code, hope this helps! I’ve added some CSS below line 481, as well as some HTML markup between lines 415 and 432.
