Clickable images in addition or instead of prev/next pager.

Saw that someone else was asking for this in the issue queue and it was suggested he add it as a feature request. Agree with the need and am doing that: Wishing to be able to advance / backtrack a gallery by clicking the images (left side / right side for back / forward ) This would be especially useful in a gallery of mixed horizontal and vertical photos, since the verticals and sometimes long captions can push the controls far down the page. Thanks!
