By accident I first bought the wrong extension from the smartaddons website (the virtuemart slideshow). After sending a mail I got a reaction in less than five minutes and a link to the right extension. Talk about service!
There are five layout themes included and you can set all common parameters to adjust everything as you please. If you want to do some more styling (for example: change the size of the titles of the slideshowtext, which can't be set as parameters) you can change it in the style.css of the module. Still quiet easy, even for me.
Last the module loads instantly on my site, even when I use 6 pictures of 60kb in the slideshow. This is worth mentioning because I have experienced otherwise with different slideshow modules.
Keep up the good work, guys!
