Data Grid 2.0 has a number of new image handling features. One new feature allows a thumbnail image to appear when you move the pointer over an image link. This feature gives the user a quick preview of the picture without actually clicking on the link.
This example is set to enable image hovering when the page is loaded. You can also disable the image hovering feature by clicking on the Disable Image Hovering button.
To see the image preview in action, move your mouse over any "View Image" link in the grid.
