For the HA image issue in forums, that's just your browser showing you an old copy of the image it is keeping. You can do a hard refresh by pressing CTRL and F5 and it should purge the old and update the new. It is changed on site though, despite what your browser is showing you.
For your HA items, I've done a HA reset, you should be able to find them now.
For the alerts issue in trades, this is a known issue that has been reported to the coders, just waiting on them to find a fix now.
