Add functionality that will pause the timer for displaying the next image (e. g. on mouseover).

The timer should resume when the mouse leaves the image area.

how can i change the background color of the imagegallery-thumbnailsarea ?

i have allready analysed the style under google.developers and found the style in rigThumbnailslst, but if i change the value in skins/imagegallery.css nothing is taken and nothing happens.
