Hmm. I've not used tooltips myself, but I'm aware of some Wikis which make use of it. Many of them employ this Java script: Dev Wiki: Tooltips

You can set waitForImages parameter to "false" and add a delay of a couple of miliseconds (if needed) to ensure all images load properly. Since the tooltips on this Wiki are not using too many images it should not take very long. Even with my terrible internet connection, the delay is barely a second long even when the page contains loads of images like this one on League of Legends Wiki.
