I am a registered member.
I have the image slider on my webpage.
The images displayed seem to be of less quality than the original picture used. I have attached one of the images that are have been used for you to compare.
In the application, Add Slides dialog, you have setup the size of the slider as 280 * 200. But on your webpage, the size of the slider is 333 * 238, that's, bigger than the original size.
Since the slider is responsive, the images are stretched to 333 * 238.
To fix the problem, in the application, you can setup the slider size as 333 * 238 or a bigger size.
If you would like to disable the "responsive", in the application, Step 4, Options dialog, uncheck the option "Create a responsive slider" (Version 3.2 and after) or "Support responsive web design" (Version 3.1 and before).
