I’m not one to use a lot bells and whistles on sites. Only when appropriate. I usually reference http://previews.xara.hosting/charity/ if I need a quick look at something.

I have a very old 1920 black and white photo of a Main Street. I also have a pro color photo of the same Main Street.
My text will read something like “Main Street then and now”. The color photo will have a revel fade in animation. Both photos the same x and y size.

My question is can I run this animation “on click” rather than a scroll reveal. The viewer would click the old photo to see what Main Street looks like now. The old photo on click reveals the new photo. I believe this could be a fade in pop up layer .
