Use specific images for Mobile not work

Hi Ced,
I use your slideshow in the fullscreen mode.
I would like to "use specific images for mobile" but I don't get it work.
I have the images for normal view in the folder "hintergruende". The Images for mobile view are in the folder "hintergruende/640". The "Max resolution for images for Mobile" have the value 640 px.
Now with a resolution less 640 px there is no image. It's only white with a loading animation.
What make I wrong?
Thanks a lot!
Michael

Hi
please give me your url to check that
CEd

Hi Ced,
the url is: www.benlex-motorrad.de . I have individual photos with 640px width on the pages
www.benlex-motorrad.de/index.php and
www.benlex-motorrad.de/kontakt
Thanks a lot
Michael

ok it tries to load
www.benlex-motorrad.de/images/hintergrue...werkstatt-termin.jpg

but if you paste this image url in your browser, you will see that it does not work. You must check why the image can not be shown on your server

Hi Ced,
until now there are only images with 640px width for the sites

www.benlex-motorrad.de/index.php ("Home")

and

www.benlex-motorrad.de/kontakt ("Kontakt")

Thanks
Michael

have you read my message ?
please check this url :
www.benlex-motorrad.de/images/hintergrue...werkstatt-termin.jpg
the image does not display. This is just an image on your website, and it must display.
That is the problem
