So I'm searching the internet for hours now and I can't seem to find the secret to CHANGING PORTRAITS. I have the software and ability to change old photos but I don't know how to set them in the frames so you see a different image as you walk by. Can anyone make a suggestion?

Do you mean Lenticular pictures?

I remember seeing a how-to that you printed out your picture in stripes, one strip was one picture the next stripe was the alternate picture, and then back to the first picture and so on. then you folded the picture into a zig-zag and glued it on to a backing.

------------------------------------ Backing

The illusion was that when you looked at the picture as you entered the room it looked one way and as you left the room it looked another. The issue is that in the middle of the room you would see both in the stripped pattern. One way to fix this problem is to control the lighting on the picture. As the person get close to the center of the room turn the picture lighting off and then back on as they are almost ready to leave.

I would agree the lenticular ones are better though!

Not sure which ones are the "lenticular" pictures, but the ones you see in the store with the plastic front are basically the same as what bradbaum described, but on a micro scale. Each fold is so slim that from directly in front you see a much more subtle blend of the two pictures rather than two drastically different pictures. Each one of those tiny plastic lines on the picture is basically a fold of the paper that brad described.

To eliminate someone from seeing both pictures when looking at the picture straight on you coud put something in front of the picture that would block the straight on view.....like a post/column

ahh thought that they were holograms now I see they are Lenticular pictures.

This would be great to know how to do it...

reading more on this. I found from this site: That Texas Magazine - Articles

"..creates a haunted version of the image by manipulating a scan of the original photo using Adobe Photoshop. Both images are digitally cut into thin strips, stitched together (or interlaced) and printed on high quality paper. Finally, the lenticular lens is applied like a laminate over the composite image to create the shifting effect."

So, where do you get the Lenticular Lenses?

A quick google search brought this up...
Lenticular Lenses Sets
But the prices! Ouch!

The other way to do it - I think Disney used it in the original Haunted mansion is with the invisible UV paint. You would need to be a pretty good artist though, as you would have to paint the evil picture on top of the good picture. then when the UV lighting is turned on you see the evil picture.

This shows one of these:

I wonder if you could refill old empty printer ink cartridges with the UV paint and use your computer to print the picture in the UV paint?

Something else you can try is a technique they use in the Haunted mansion for the portrait over the fire place. They have a couple of slide projectors set up pointing at the same reprojection screen mounted on a picture frame. One projector's image will be showing on the screen while the other is ready but the light is turned down. The image is then cross-faded from one projected image to another.
