I'm adding a css tooltip to my website. Using it, i'll be able to show the information of a particular image. I've found something called qTip and the tooltip is easy to add. However I wonder if they are a good idea overall - do you think it is worth adding? One thing I see is that, using Opera, the image link shows up in a standard tooltip, which covers my own css tooltip. I'm sure it's not a big problem but I'm wondering whether to add it all now. Any thoughts?
