How can I change quality of images in professional slideshow software?

Q: To insert the images in the slideshow worsens the quality of pictures massive! How can I stop this? This is a real problem! Thank you.

A: To improve quality of your images you can do the following:
1) Go to
Gallery->Properties->Images

and increase value of "Image quality" parameter.

2) Use original images with the same resolution that your slideshow should have
(300x220). wowslider app. is not graphic editor, so the best way to resize your images is
use of special products (for example, Photoshop).

3) wowslider app. generates images in .jpg format. So, if your original images will be in
.jpg format too, i t'll help to save quality of original images.

Also, quality of images doesn't depends on dpi and there is no "minimum size for best quality".
