Preloaders is a site that allows us to create images of charge online in various formats. Useful to make visible while the content of our (or part of it) is loaded. Think about where to use it, because in some cases they do not make much sense. However, when part of a new project and we know that weight is going to take, the better to show for it is known that lack content to appear.

Upon entering you can choose the way (there are several interesting models available in a dropdown menu), the background color or if you want transparent, the color of the image itself, the size and finally the animation speed. So if you want a custom image load, is one of the best options.
