1. Place the image you want to display with a hover
2. Place the image you want to display in normal mode on top of it. Set the width and height of the overlaid image to 100%. (If you are placing overlapping images, first increase the size of the parent image to make it easier to include.
3. Select the normal image installed in step 2 and click on the Hover of conditional styles. And set the transparency to 0.
