Thumbnail problem

The css from your theme is stretching the width of the image. Add this to the css of your theme to fix it.

#nwm-outer .nwm-destination-list img, #nwm-outer span.nwm-circle {
width: auto !important;
}

You can change the height of the map by modifying the css file as well.

#nwm-outer .nomad-world-map {
 height: yourvalue !important;
}

.nwm-destination-list {
 height: yourvalue !important;
}

There is currently no way to disable both the tooltip/slider, or make it auto scroll.

Try this

.nwm-destination-list {
min-height:0 !important;
height: whatever !important;
margin: 20px 0 0 0 !important;
}

Try this:

#nwm-outer p.nwm-travel-schedule {
font-size:12px;
}
