To many images = Page does not load

Hi,

For a while now I′ve been using Pinboard on a furniture display website, unfortunately I′ve noticed as I add more and more models to one page (i.e. pictures) the page eventually does not load. At first it was just slow but this wasn′t an issue as I had forgotten to install wp super cache, the speed issue was solved, about a month later though, the pages with a lot of images just would not load (25+ images, which doesn′t seem like that much), it only seems to be happening with pinboard, I′ve tried using the jetpack carrousell in case it was a pinboard lightbox issue but to no avail, what can I do?
