Images from ter-hoster break SSL address-bar in the browsers + CSP
Normal i have a secure connection in backend, but images from ter-hoster are http from typo3.
typo3 has also https.
Because of the frames and ajax the address-bar won't be restored in SSL design.
I know SSL is still active, but somebody else maybe don't know it.
The next problem, if you use CSP and say no external images and frames....
Maybe add images in typo3 package or load it with php and save it in typo3temp.
