FAQ

What is the Nextgen NivoSlider plugin?

Itís a plugin that allows you to use a NivoSlider in WordPress by using a shortcode. It allows you to populate the NivoSlider with images pulled from your NextGen Gallery by gallery ID, image tags or simply everything!

The resizing options are not working, why?

You may need to give TimThumb’s cache folder permissions by using CHMOD 775.

How come the effects aren’t working?

In order for the effects to work the max-width of “.nivoSlider img” needs to be none. By default this will be set as !important, however it might be that you altered the CSS and that another stylesheet is overriding the style.
