When a new visitor enters the gallery for the first time they see instruction pop-up boxes of how the gallery works. Currently I have to explain the functionality of the gallery to the one (or few) recipients I email the gallery to. If they invite friends and family they are not getting my instructions of how things work. Three of four pop-up boxes that point out the main features would be amazing and help generate sales plus less frustration for visitors visiting for the first time. This would take IP to the next level in my opinion : )
