Hello expert and friends!

I Use wincc 7,5 and want to use the web navigator. I did all the steps (web publish, web configurations) and install all the required add-ons or programs to run the program online. But when i input the IP address on the IE 11. The screen just showing some wincc control panel without my pictures in it. I search every menus to find it, but no luck. theres no picture in it. I swear i publish them but i cant find it.

i try to copy the web link url each pictures on wincc explorer into clipboard and paste it to the IE 11, it just shows blank page with X pictures on corner left.
