So my case is, I need to verify this email which is sent from address wowaccountadmin@blizzard.com.
It said earlier that my account had been logged in 5th of this month even though it had no game time, so I think it's fake (Account cant be logged in without game time I'm sure you know this.) I can log my account fine in eu.battle.net if that's any help.

Yes, it is safe if you consider any imageshack file safe. You don't have to open it.
