Hi,

I am keen to buy the pro version but I want to make sure it can do one thing before I do...

Is there some css or javascript trickery I could use to hide the main image and only show thumbnails, and then when a thumbnail is clicked have the main image come up and hide the thumbnails?

I would probably like to have 20 or so thumbnails taking up the whole screen in 5 rows, and then when a thumbnail is clicked and the main image opens the thumbnails revert to 1 row of four (scrollable) at the bottom.
