RSS dynamic slide generator doesn't show image

An RSS feed is not equal to the content of a website! It is only part of the website's content, what the website's owner allowed for people to ask down through that RSS link. You should go to your RSS link, and you will see every single data there, which is accessible. If there is no image, then you won't have any images!

You can check your feed for instance, with Firefox, which shows it in a more user friendly way. Simply open the RSS link, like you would open any page.
