in the galleries/grid_fullsize/gallery/gallery.js file, find the following code:
//tooltips
this.tips = new Tips(this.thumbs.images, {
className: 'pg-gf-tip',
offset: {'x': -100, 'y': -105},
showDelay: 1,
hideDelay: 1,
onShow: function(tip) {
this.options.offset.y = this.tip.getSize().y * -1 - 15;
this.tip.setStyle('top', (pgMousePosition.y + this.options.offset.y) + 'px');
this.tip.fade('show');
},
onHide: function(tip) {
this.tip.fade('hide');
this.tip.setStyle('top', '0px');
}
});
and change it to:
//tooltips
/*
this.tips = new Tips(this.thumbs.images, {
className: 'pg-gf-tip',
offset: {'x': -100, 'y': -105},
showDelay: 1,
hideDelay: 1,
onShow: function(tip) {
this.options.offset.y = this.tip.getSize().y * -1 - 15;
this.tip.setStyle('top', (pgMousePosition.y + this.options.offset.y) + 'px');
this.tip.fade('show');
},
onHide: function(tip) {
this.tip.fade('hide');
this.tip.setStyle('top', '0px');
}
});
