No program has been devised to artificially inflate views on your photos. A view is a view, and impression is how often the thumbnail was viewed/displayed. As to why some photos have a burst of views shortly after upload then it trails off - its likely because "recent uploads" is one of the most popular areas of the site and they click on the thumbnail thus generating the view....as time goes on a less recent upload resides further down the page therefore likely generating less views. Generally speaking, the more frequent you upload a photo - the more your portfolio gets viewed because the recent upload can spark curiosity and lead the user deeper into your other galleries. I hope this helps.
