Slideshow with no automatic sliding?

You can try adding this to:

GD>Design>Scripts>Footer Script

<script>
jQuery(window).load(function() {
if(jQuery('#geodir_slider').length){
jQuery('#geodir_slider').flexslider("pause");
}
});
</script>

You can hide the slider, is that what you want to do?

TO hide the slideshow arrows try:

.geodir-control-nav,
.geodir-direction-nav,
.geodir-slides .clone {   
    display: none;
}

.geodir_flexslider .geodir-slides img {
    float:left;
}
