Yep, this issue is back, i still get this lag on loading images since a week in a row, but not the whole day like in the past, only during certain hours, expecially evening. Resetting the browser somehow help and log-in again seems to only temporary solve the issue. Guess they have issue with caching again or is a routing issue in certain parts of europe, never knew what was the cause nor in the past not now, maybe bandwidth saturation.
