Loading time

I am using version 1.37 of Image Show GK4 and for testing purpose using just 1 slide.

The loading time of this image slide is pretty long, it seems longer then necessary. It looks to me it's only delaying. It doesn't make a difference when setting cache on or off, or loading small or big image. Of course a little, but the loading is delaying.

Is it possible, like other slider extension, to set to delay time myself?

The module have some delay to make sure that all images are loading properly. In other case it will cause JavaScript errors and there is no easy way to modify the loading time.
