Change anchor image opacity on hover

Hi to create a mouse over effect you would have to add some javascript code. Currently the plugin has the option to add an opacity level in the settings.

If you wanted to add some opacity to the thumbnail image, you could add the following CSS code to the following class .wpvl_auto_thumb_box. But this does not produce the mouse over effect that you are looking for.

.wpvl_auto_thumb_box {
    height: 150px;
    position: relative;
    opacity: .8; <---- I added this
    width: 200px;
}
