That was my exact experience! No shit! It was as if the picture transformed into the two women right before my eyes. Literally! HA!
As you are looking at the picture, if you can let your line of sight get very diffuse, the JC picture will appear. Try not to stare at any particular point, but rather let your eyes relax. For me, I also try to relax my mind, not thinking about anything in particular. The whole mind part isnāt one of the usual directions for these types of pictures, but I find it helpful.
Good luck!
Edit - Itās a little weird, but to me when itās JC, it looks as if heās got half a pizza hanging from his chin.
Fixed it for you lol
Unfortunately for most-- it happens at your funeralā¦
Those do not work for me most of the timeā¦ multiple reasonsā¦
Iād kill for a squiggley arm com8ng out of my forehead or abdomen. A little one, just to hold stuff close, so I can see it. Then itāll work for me. 
And I want two thumbs on that hand 
Two index fingers. Pinkey, youāre out. Two ring fingers, in case I get bored, which I wonāt, because I have three arms, na na na boo boo
Iād like a prehensil tail
Yet only five fingers on a handā¦ Why limit yourself like that?
Frankly I lost count at 14
Honestly, completely understandable to my simple mind. Numbers are so confusing to me.
The pinkey gets relegated to the back of the hand like a raptor toe, the middle arms slaps impressions will be fancy
Iām able to clap with one hand so others can hear it. Actually, I can do both hands independently of one another. (I taught myself to do it as part of a solo juggling trick none of my juggler friends could do.) Clapping with the raptor toe hand could be interesting. Just donāt hook yourself!
