I often display one single column of images in my tables. It is annoying that the tooltip shows up by default all the time as the image is self explanatory and has no other details. It would be very handy to have the ability to turn the tooltip off if one so desired.

In Cross Tables too. There's generally no need for a tooltip in a cross table that annoyingly displays the same value I can already see in the cell. Ideally the cross table would have normal Tooltip properties available like other visualizations, so that I could add additional custom drill-down calculations when hovering over cells.
