images are blurry

I added two slides
I add the shortcode to a page
I display the page and see the slideshow
Images are blury

Since the only option when adding a slide is to add a featured image, that grabs the thubmnail image so when it is displayed on a page it is enlarged and blury.

Sorry but your plugin – in it’s current state – is heading for my trash can.
