A flash slideshow has to be developed that …
1) slides images like here:
http://www.elbresidenz-bad-schandau.de/de/spa-and-medical-wellness/
2) the flash movie imports the images from a textfile, so that the slideshow images can be changed easily.
After sliding the last image the first image comes again fluently.
If we specify only one image in the textfile then the image slides in and stays without any more sliding.
3) An animated line like in the link above also has to be included.
