Preloader Maker is an amazingly simple way to preload Website images. Preload Bmp, Gif, Jpg, and Png images for your Website in one simplified step. Just type in your image filenames or right click to copy and paste. You can edit existing entries and delete unneeded filenames as you wish. The preloader code is generated instantly. How does it work? Browsers are designed to optimize the downloading of images during the document load/parse phase. "Preloading" loads an image file into the user's computer memory so that it can be instantly accessed when needed. This is useful, for example, if you have a mouseover event and an image that needs to change without any delay. Your images will open faster and rollover effects can appear to have a seamless look when preloaded with Preloader Maker.
