If I change the document thumbnail, the image is showing up in the access-point. But If I use the same image as a textfieldbackground it isn't showing up!
If I open the dashboard in my destktopsoftware and turn on the webview. If I open the first time a tap, the images are not showing up. If I go to another tab and than back to the first tab, he is showing the pictures(text-backgrounds)!!
