On a webpage I have a upwards of 2000 images, the majority of the images through javascript are not all displayed at once and are separated into a new page that is hidden every twenty images. However these images are all loaded (Served by PHP) on each request. These images are stored externally on a clients host.
What I would like to know is what effect loading a large amount of images like this would be on the clients server if the site were to experience a boom in traffic? Would there be a high risk of taking their servers down or is something baked in on the webserver to prevent such a thing occurring. Caching etc.
