Note that waitSeconds should be large enough to load all the images, otherwise module may timeout.
Use this plugin only on specific cases and make sure you set a large waitSeconds (default is 7 seconds).
!bust to the file name will avoid caching the image.!rel to the file name will load image realtive to baseUrl or module path.!bust flag, so you may need to clone the image element before inserting it multiple times into the same document.
