Sorry, but I think your answer is insufficient. I should tell my visitors, that they shouldnt resize their browser window (and switch to a mobile device), otherwise the slideshow will not work or make strange behaviors? For me as agency my task is to show the best user expieriences with all user behavoirs included. And of course the normal behavoir is not to display a website in a resized window but it CAN happen and thats reason enough to fix the problem. So I will use an other image display for this case. Thanks anyway.
